KSU Storylines

Hey guys, I have Finn, Artie, and Santana, who would ALL like to be more active, but, I've brought them in from different times, and I know you guys have all brought your kids in from different times too. It makes my brain all fuzzy. Can we just do a quick heads up on when we all are, I'm thinking about changing my timetable if most people are in the same place.
