DPxDC - The Bat Key

there were a few posts going around a bit ago about Danny being Bruce's mentor in his early years, and they planted this idea in my head. i mixed in some cryptid danny for fun and to fit the halloween vibe. also on ao3

Batman grunted in pain as he hurried down the dark, townhouse-lined sidewalk. The cloudy night blocked the moonlight, and the lamps along the entire street were out, but they still moved between the shadows under the trees. The slash wound in his side was painful to the point that he had an arm around Robin’s shoulder to prop himself up. He scowled with each grunt. At least the blade hadn’t been spiked with venom. The same couldn’t be said for Red Robin’s wound. He was barely conscious, and Nightwing had to practically carry him. But they had finally made it here.

“Door.”

Nightwing hobbled up the few steps to the small porch and leaned against the wall to help hold some of Red Robin’s weight. Robin rushed to the door, already pulling a pick set from his utility belt. Batman managed to ascend the few steps himself, double checking the 13 to the side of the door.

“Wait.”

Robin scowled once again, but he complied. Batman pulled a small strip of metal from the lining of his utility belt. The tip was cut into a jagged, hooked pattern. He slipped it behind the bat symbol on his chest from underneath and twisted it a half spin. When he slid it back out, there was a house key attached to the end. Once free, he inserted it into the deadbolt and removed his hand. The temperature immediately dropped. Batman sighed in relief.

“What are –”

Robin’s question died before it was finished as the key began glowing green. It slowly rotated itself with the sound of grinding gears until a click echoed from behind the door.

“Oh great, I’m hallucinating” Red Robin wheezed out.

Batman turned the knob and pushed the door open.

“In.”

Robin entered first, crouched and alert. Nightwing followed, Red Robin draped over his shoulders. Batman took one more look around and spotted one of their assailants across the street, staring with their two glowing yellow eyes. He held the gaze for a silent few seconds, tension slowly leaving his body as they remained deathly still, then stepped inside and closed the door.

The large circular window high above the door lit the entryway with moonlight from the clear night sky. A staircase on the left led up into the dark, its railing marking out a small hallway balcony above. To their right was a small table, empty except for an unlit lamp. Past that on the same wall was an archway that led to a dark room pierced just enough by the moonlight for a large couch to be visible. The hallways straight ahead stretched into void.

“Couch.”

Once again, Robin entered first, disappearing into the shadows to scout the room. Nightwing lugged Red Robin into the room and laid him down on the couch to examine his wound. Batman followed and watched over the back of the couch.

“Bruce.”

Robin spun and threw a knife at the voice.

His senses had been honed to perfection since as long ago as he could remember. From the age of eight the only two members of the League who were capable of sneaking up on him were his blood relations. Now that he was out, Cain was alone on that list. Not even Batman could go unnoticed. Whatever this voice was, it managed to surprise him. But the League taught him to have no weaknesses, so even if his senses failed him, his reflexes could pick up the slack. The best tutors known to man had trained him with strict discipline, instilling perfect form and pinpoint accuracy that he could replicate from a dead sleep in pitch black darkness, all before he had even formed a single thought.

All together, this meant his blade was in the air before he could even parse what was said or what tone it was said with. When he realized that the voice had called Father by his civilian name in a calm greeting, he realized he made a mistake. But luckily, the voice wasn’t injured. Nor even startled.

“Danny.” Bruce greeted back.

This Danny had caught the knife by its handle well in front of his chest with what Robin evaluated to be his off-hand. Bright blue eyes pierced through the darkness straight to his position. They glowed in the darkness despite emitting no light, almost like a cat’s but without a source to reflect. If he had to guess, this unknown was a bit older than Red Robin. A bit taller, too. His deep black hair was unkempt, as if he had just been in a windstorm, sticking up at gravity-defying angles. He wore a dark robe made of fine material, not quite up to League wear standards, but too formal for a nightgown.

Robin cautiously stepped out of the darkness toward the others. Danny’s squinted eyes followed him, head angling slightly as it rotated to track his movement. Then they flicked away to look at Nightwing and squinted further. After a scant two seconds that stretched far too long, he raised his other hand to push his sleeve up, revealing a cheap plastic Batman-themed digital watch with a bright blue rubber strap.

“Been a while, hasn’t it?” He murmured.

He pushed his sleeve further to reveal another, different watch, analog and much more elegant with a black strap most likely made of leather. It looked like something Father would wear to a gala. His eyebrows raised as he looked at it.

“Late, too.”

Batman grunted. Danny dropped his arms to his side, grip loose on the knife. He dipped his head at Damain and looked at Batman.

“My son, Damian.”

Damian tensed at the revealed information.

“He’s sharper than you were.”

“Being raised in an assassin cult will do that to you.”

Damian tensed even more despite the relaxed familiarity, almost teasing tone, that Batman fell into. Danny hummed a deep note and nodded his head toward Nightwing.

“Dick?”

“Nightwing.”

“And the one bleeding all over my couch?”

“Red Robin. Tim. Also my son, not by blood.”

Danny hummed again and lazily tossed the knife into the air toward Robin (who easily caught it, of course) as he walked to the other side of the couch. His movement made no noise whatsoever. Nightwing stepped back cautiously, positioning himself to step between Danny and Red Robin at a moment’s notice.

“What kind of poison?”

“We don’t know.”

He sat down on the edge of the couch to look down at Red Robin but paused as he was leaning down. Instead, he pushed up his sleeve again, and the watches were gone. In their place was some sort of wrist computer that took up half his forearm. The screen was covered in undecipherable text and was surrounded by several buttons marked with hieroglyphics. Robin narrowed his eyes and gripped another knife behind his cape.

“If you throw another blade, I’m confiscating all of them.”

“Stand down, Robin.”

He scowled but let go of the knife. Danny looked to Batman.

“You seem to be getting a call, Bruce. You can take it in the entryway.”

Batman nodded and walked back out the archway, tapping his comm.

“Oracle. We’re safe for now. Red Robin is being treated for poison”

Robin and Nightwing watched him go, turning back after a brief second, only to flinch into defensive stances.

The entire room had changed. It was now lit by a blazing fireplace with a large coffee table between it and the couch where Danny and Red Robin were situated. The table was covered in supplies – glass bottles with colored liquid, mason jars filled with water and fruit and herbs, bowls of nuts, trays of fruit, plates of granola balls, and stacks of labeled first aid kits.

They each stole a look back to Batman, who kept speaking over his comm, not bothered in the slightest.

“I know you can’t. Have the others pull back.”

He flashed them the hand signal for safe.

“I’ll explain when we return. Hour at most.”

They focused back on Danny to see that he had a much larger first aid kit open on the floor next to him and was skimming his fingers across Red Robin’s forehead, brushing his hair away.

“Oh, this one’s cute,” Tim slurred, and he was Tim now, his mask resting on his chest.

Danny snorted and shifted Tim’s uniform away from the slice in his side. He wiped the blood away with some bandages and tilted his head in confusion. He lifted a bloody finger to stare at it. His eyes squinted and he brought the finger up to his nose, where he gave it a sniff. A low growl vibrated through the room, and Robin gripped his knife again. Danny tapped the bloody finger to his tongue, and Robin threw his knife. Or he would have, had Batman not caught his arm.

“Well?” Batman asked.

“It’s a good thing you brought him here,” Danny responded, voice deeper than even Batman’s, “No one should have access to this.”

He raised his other hand and a glowing green post-it note shimmered into existence in his palm. He flicked his wrist toward Nightwing, offering the note to him between two fingers. It was now covered in tiny writing, just as indecipherable as his wrist computer had been.

“Take this into the greenhouse,” he nodded to a door behind Nightwing that had almost certainly not been there before, “Give it to the Gardener; she’ll get you what you need.”

Nightwing hesitantly took the note and looked to Batman, who nodded to him and began walking to one of the chairs next to the couch. He stepped backwards to the door and cracked it open, giving them all one more glance before slipping inside and closing it gently behind him.

Batman slipped his cowl off and grabbed one of the bottled drinks, twisting the cap off and taking a large sip.

“I’ve tried countless times to replicate this flavor, all of them unsuccessful.”

“It’s made with long-extinct fruits, Bruce. I’d be impressed if you managed it.”

Bruce grunted as the door behind him opened and Nightwing stepped in, looking slightly shell-shocked, carrying two small jars and no post-it note.

“Took you long enough,” Danny scolded while gesturing him over.

He handed the jars over and sat down in the chair opposite Bruce, squinting in confusion at his lack of cowl and relaxed snacking. Robin slid into place next to him, still tense and on guard.

Danny unscrewed one of the jars and stuffed a roll of bandages inside before screwing the lid back on. He tossed it to Bruce without looking (who easily caught it, of course) and unscrewed the lid off the other jar.

“Help yourselves, by the way,” he vaguely gestured toward Robin and Nightwing with his head and pointed to the table with his elbow.

Bruce shook his jar and pulled some of the bandages out, sliding them underneath his suit around his wound. Danny scooped a finger’s worth of paste out of his jar and spread it over Red Robin’s wound. He screwed the cap back on and tossed the jar to Bruce just as the other one came flying back to him. They were both easily caught, of course.

Despite the initial hiss of pain, Red Robin’s whole body had been relaxing since the paste had been applied. His eyes slowly opened while Danny was cleaning his hands off and flicked around the room in a quick assessment.

“Who’s this?”

“Danny.” Bruce supplied.

Red Robin looked around the room slowly this time, taking in Bruce’s cowl-less head, the half-drunken jar of colored drink in front of him, the pile of nuts in his hand, Nightwing’s slightly traumatized face and awkward posture, Robin’s irritated scowl and distrustful glare, and he groaned loudly.

“Please tell me this isn’t another Selina situation. He’s like my age.”

“Bold of you to assume my age and gender.” Danny deadpanned.

Red Robin gaped back.

“I met Danny when I was first starting out as Batman.”

“When he was what, eight?” Dick blurted.

“Still with the assumptions,” Danny muttered to himself.

“We thank you for your assistance...Danny.”

Robin was stiff and formal and struggled through the Danny. But that didn’t stop Danny from giving him a slight smile. He looked down at Red Robin then up at Nightwing then finally back at Bruce.

“I like them,” he declared, grabbing a jar of water off the table.

Bruce grunted as Danny unscrewed the lid and handed it to Red Robin.

“Danny has not aged since we first met.”

“Not exactly, but whatever,” Danny mumbled as he tidied up the first aid kit.

Nightwing opened his mouth as if to speak but shook his head and kept quiet. Robin stepped forward to grab a banana off the table with a polite nod to Danny. Red Robin stared down at the jar in his hands. It was full of cold water with a thick slice of pineapple and sprig of mint. After a quick glance to Bruce, he took a sip that turned into a gulp that turned into him emptying the jar in one go and releasing a contented sigh afterwards.

“Do you know anything about the Court of Owls?” Bruce asked.

A tremor shook the house. Bruce tensed in reflex but didn’t leave his chair after a glance to Danny. Nightwing leapt to his feet. Robin slid backwards and drew a blade. Red Robin jolted up and winced through the half-eaten pineapple slice in his mouth. There was a tense silence for several seconds.

“Only that they are not welcome in Gotham,” Danny eventually replied.

After a few more seconds of silence, Danny flicked his eyes to the fireplace mantle as a small object tipped itself over. Nightwing shot his hand out and snatched it out of the air before it could hit the ground. He opened his fist and looked at a miniature gargoyle statue in confusion.

“I may have to become involved,” Danny nodded to Nightwing, who gently replaced the gargoyle on the mantle.

Bruce grunted. Danny tilted his head, staring into the middle distance.

“The occult shop on 4th and Finger between Asher’s Deli and Panadería Golosos,” he recited.

“There is no such shop.” Robin scowled.

“You are correct,” Danny turned to look at him, “And now that you know it’s there, you’ll be able to find it.”

“Emergencies?” Bruce asked.

“Entryway table, same rules.”

The exchange seemed to satisfy Bruce, who stood with a grunt and pulled his cowl back over his head. The others rose with him and followed him toward the entryway, each nodding a thank you to Danny as they went.

They stepped back into the moonlight of the entryway and saw the previously empty table now had four keys laid out on top of it, evenly spaced and covered in a thin layer of dust. When they looked back through the archway they came from, they saw a dark room back to its original form, no Danny to be seen anywhere.

Batman grabbed one of the keys and slipped it into a belt pouch. Robin followed his lead and took a key for himself.

“Father, were you ever going to inform us that you befriended a vampire?”

Batman grunted and cracked the door open to peer out.

“He’s not a vampire,” Red Robin scoffed, grabbing a key for himself.

“I don’t know, creepy house, magic shit, you should’ve seen the gardener,” Nightwing swiped the last key with a flourish.

“He tasted your blood, Drake.”

“He what!?”

“That was after you called him cute,” Nightwing teased.

Red Robin froze with his mouth open, eyes slowly widening.

“I was hoping I just imagined that.”

“Seriously Tim, he’s probably like 300 years old.”

“Tt, I believe Brown would call this robbing the cradle.”
