Kelly will be tossing raptors everywhere. Want your character to get beaten up and need someone to rescue them? Kelly's your girl! Let's see how the giant Spartan super-soldier deals with being able to kill non-human things again 8D She doesn't particularly care about the wardens and their rules so she won't be as hesitant to stop these threats as some people might be.
Helen will be on duty at the clinic for the most part, once she figures out things are going down, so if your character needs medical attention and they don't want to head for the hospital (or can't), the clinic in Sector 3 is always open! Fellow medical personnel want to talk about things going on? I'm open for things here!
Liz will be on her own duty in Sector 0, once things start happening, though once it's a little more clear that she might not be the best choice to fight these things, she'll focus on helping anyone get out of harm's way.
I'm still technically on hiatus, but I'll be done with finals by the time this rolls around so I'll be a lot more free and less stressed if anyone wants things with my three! More than open to plot things out! As for fear effects, all three will likely be affected to varying degrees. This totally bodes well for the Spartan y/n/oh shi-
