In love with how the gang interacts with one another's dragons.
Like, these dragons are their friends too just as much as their own are.
Tuffnut will give Toothless high fives and talk to him, Astrid will bring Hookfang fish and laugh with him at Snotlout and they'll give each other's dragons nicknames and communicate with them like friends and Hiccup will be sassy at Barf and Belch and he loves all dragons so so much but especially the ones he bonded with first and they're so close to him and one of the riders will look after Meatlug if Fishlegs is unavailable and share a look with Toothless when Hiccup is being stupid and they'd get so protective of Hookfang, Tuffnut will tell them bedtime stories and Snotlout will vent to them and Hiccup treats them like one would humans and Fishlegs will infodump about something to them and Astrid will give them The Look™️ that she gives her friends if they're being stupid and Ruffnut will involve them in her prank plans and they all talk to one another's dragon like those dragons are their best friends and any of them would recognize one another's dragons even in hoards of wild monstrous nightmares or nadders or gronckles or zipplebacks
I'm just so normal about the gang and their dragons.
There's one line in Race to the Edge, just one line, that made my respect for Snotlout spike. I don't remember the exact quote, but they were all under attack, and Tuffnut asked Snotlout why he was hiding out in their hut instead of his own,
And Snotlout's response was something along the lines of, "I was so busy reinforcing everyone els's huts, I forgot about my own!" And then cries out in fear from another hit of a catapult lol.
