#and with the cable guy she absolutely still had a healing brain injury

[normcore-tertiary-character]

One thing I really wish they'd leaned into on Ghosts was early on excusing all her ghost-related behavior as being because of her head trauma at the start of the series. In the first few episodes it would make more sense if she was leaning on that reasoning for her weird behavior, particularly when she does think the ghosts are concussion hallucinations. Then when she gets in a pinch like with the Farnsbeys where she's probably healed but acting really weird it would be a reasonable way to try to shrug off some suspicion.

Then she just gets used to it as an excuse and it crops up in increasingly ridiculous circumstances. She tells the waiter at her mom's diner that she's talking to the air because of a head trauma. She tells Mike like 6 months into his working for them. In season 2 she tells guests who walk in on her talking to herself that it's due to a head injury. Eventually she's so used to all ghost things being because of her head trauma that someone sees the lights flickering from Thor and she's like "hey, sorry, I have a concussion"
