I'm glad you liked my idea and I LOVE YOUR BRAIN! I'm mizixy on AO3, I don't have tumblr so I'm stuck on anon (I'm also the Sense8 crossover anon). For more food for thought, what are Laura and Allison's mental states? All the trauma they underwent. Laura has been gone for so long, but where was she? Was she at peace with her family or fighting in Purgatory? Does Allison fingers tremble every time she picks up a knife, feeling the echo of the Oni's blade in her gut?
And ooh I’m definitely with you on that. They would both be going through some intense trauma recovery post-resurrection. Even if they couldn’t remember their time in the afterlife, the memories of their own deaths would trigger a lot of emotional issues. Will they be able to sleep without dreaming of being torn open? Will they be able to fight without the memories paralyzing them? Will they be able to kill if necessary, after knowing what it feels like to die?
Not to mention simply readjusting to being alive again, and learning about everything that’s happened in the interim. Derek would probably be older than Laura by this point. Every paper and document and person she’s ever known would say she’s long dead. And she’d have to deal with Peter’s betrayal, with Cora being alive, with learning about everything her siblings have been through while she was gone.
Allison died in the arms of her first love, and will come back to find that he’s officially moved on, and not to mention how her newer love interest fled to France after her death. She and Chris would have to learn to navigate each other again when probably every instinct Chris has would be screaming for him to lock her away in a protected space forever so he won’t lose her a second itme.
They would definitely have more to deal with than outside threats.
