Godric - He'll be staying late in his office when it hits, so he'll be on campus for the week, staying in Blake's campus apartment (more than likely with Hope).
Garret - Late shift, he'll be there throughout the duration as a rare staff member completely unaffected.
Lyle - Since Lyle lives on campus, ovbiously he'll get hit by it. He doesn't go out much when he feels fine, so he's probably gonna still be reclusive.
Mandy - She's hiding from her parents so she'll be off campus at Rorie's house for the week.
Blue - She'll be getting hit the hardest. Not only will she get sick, but she never hit puberty as a human so she's gonna grow like crazy- we're talking going from 5'0" to 5'10" within the span of ten days.
Penny - She and Blake are taking a vacation on a cruise and they'll be very far away from this whole mess. Lucky fuckers.
Ari - If anyone wants to see him actually shut up for ten seconds, now is the time. He probably won't leave his room, and there's a 40% chance I'll kill him off.
Max - He's with Mal, sick as hell and probably crying a lot because he doesn't understand what sickness is.
Billy - Another staff member who won't be affected.
June - She'll be sick too, one of the worser cases.
[Edit]: Oh I forgot to mention! Kimmi (Mandy's mom) will be on campus when it hits, so she'll get stuck too. And she'll get a little sick... ^_^
