Figured this might be a good place to post info about what charas are doing and how they will be impacted, so I'll start!
Starbuck - He'll be a big baby over being sick (since it's never happened to him before), but only at first! Once he realizes that Kamea is aging rapidly and Kim's pregnancy is accelarated, he will push through the sniffles and stomach ache to try and take care of everyone. Kamea will be nearly seven years old by the end of the plot, and I already have a new face for her. Will be making icons soon, woot! Also, as mentioned, Kim's pregnancy will speed up, and by the end of the plot, she'll be just a few weeks away from delivering sweet baby Reed. YAY!
Frankie - She actually HAS been sick before, even though she's full blooded fire sprite. Because of Frankie's crazy emotions, she sometimes gets overly cold, and that can cause her to feel ill, but she's never been sick to this extent. For fun, I'm going to have her sneeze fire :D So you might want to keep your distance! She's gonna be super sick, so expect her to mostly stay in her room.
Nox - Since he's a full blooded demon, he will be a WRECK! I doubt he'll be capable of leaving his bed for most of the plot, though he'll try, because he thinks he needs to help others and all that jazz. I'm guessing Belle and his friends will have to convince him that it's for his own good and the good of others that he stay in bed.
