(continuing the conversation of ghostlyhabato’s post here)
I think the Christmas episode doesn’t prove it enough. Yes, there is a Christmas Truce where they don’t outright attack each other for a whole day. But then they’re back to fighting and shooting blasts and trying to decapitate Danny for the next 364 days. Even if they can all be friends for a day out of the year (even if this is all a big joke or playing or roles for the ghosts who would otherwise be perfectly content to not attack anyone all year long, which I don’t think the show supports), that isn’t enough.
Not only do they have to not attack Danny, they have to not attack anyone in Amity Park. They have to not come out of the portal at all. And it has to be unanimous. No Spectra sneaking out on her own to cause havoc when Danny’s not up to stopping her. You think ghosts are going to start fighting each other on the humans’ behalf to keep other ghosts from going through the portal? I don’t think so. Not just because the halfa’s family got blown up and now he’s depressed. Especially without knowing about what Danny almost turned into in another timeline.
As for Danny staying with a ghost to live? I just… I can’t see that working well for anyone. Even if he finds a “good ghost” like Clockwork or Frostbite or Wulf… like he can’t talk to Wulf, Clockwork isn’t supposed to interfere with time and he’s already done it enough by saving Danny and Danny hasn’t even met Frostbite at this point in the timeline and he pretty much kept destroying stuff in the Far Frozen when he was there I am not sure how welcome he would actually be to stay permanently.
Plus, while I am all for writing ghosts with back stories who are more than just stereotypical cartoons, they are GHOSTS. They are dead. They don’t know what it means to be alive or what that entails. They can’t provide the food or shelter or social interactions that people need in order to survive without going insane. And they are OBSESSED with something. It is in their nature. Can they really break from that long enough to care for a depressed, self loathing, can’t-do-anything-more-than-stare-at-the-same-photograph-all-day member of another species? I don’t think so. At least not without bad things happening to Danny. If he’s stuck trying to recover under the care of an obsessive spirit, how much different from Dan do you think he’s going to end up being in the end?
