Sally Ann I'm guessing would have been taken to Moody's. She alternates between sleeping and staring at the ceiling. She's not very good company to be around, so I apologize to anyone who has tried to visit her. She's just... caught up in her own little world. Plus, she just doesn't want to hear anymore bad news so detaching herself from the reality around her is the easiest way she can see to pull that off.
Rose will probably be at Moody's too, since she's one of the extremely sick ones. When the fires start if she sees it, she's going to start freaking the fuck out and probably need to be put back to sleep, much to her utter dismay. To her, this is totally like... the end of the world, the book of Revelations, coming to play out. She thinks the fire is there to smite all of them.... Yeah. She's weird like that, I'm sorry.
Amelia is angry. She's also probably at the vault. She is ready and willing to do whatever anyone needs whether it be collect food, water, medicine, or kill things. Also, once the sounds start at night... if anyone is going out to investigate she WANTS TO BE PART OF IT. JSYK. Because she is not going to sit around while their world fucking falls apart. Because she likes world a lot better than her real one... sooo.. she'll fight for it. Sorry Eddie. I know you want to keep her safe xP
Rabastan and Amelia are strangely on the same wavelength with this one. Rab isn't slated to be a hero still, but he is more than willing to go check out noises, help people, make supply runs, what have you. He IS a little irritable because he's out of nicotine, so beware of that. He is also at the vault... because Rab... Moody's house... no. xP Oh, and if Nathan needs any help being a general badass, Rabastan says sign him up too. So there's that.
Polaris is where ever Lily is? I'm assuming at this point it would be Moody's, but I'll let Amber decide that. She's still playing with her new doggy, taking naps on him, showing him to anyone who will give her the time of day, and probably playing with whatever random objects she can get her hands on. When the fire and noises start, I can see her shaking and cowering because she's terrified they're all going to die or get hurt. Yes, she is well aware of what has been happening. After all, people are extremely sad or sick or haven't been around, so even for so young she has put two and two together. She'll probably be attached to whoever she knows and is closest to her. So yeah :)
