For Cel, it’s pretty much no problem as long as she gets a warm cup of joe the morning after. She’s used to spending late nights at band practice (read: partying) until the wee hours in the morning, then clocking in at work three hours later, fresh as a daisy.
Perp, on the other hand, can just not function if she doesn’t get eight hours a night. If she even tries to wake up earlier, she’s pretty much a zombie for the whole rest of the day… which kinda sucks whenever she gets an evening shift and a morning shift back-to-back. She does try her best to stay awake, at least, and that’s what counts!
