The window's locked.
Prism's brow furrows from where she hovers in front of the window to team Casanova's dorm. She'd left it unlocked when she went to the library earlier that night, and now it was nearly 3 in the morning - the perfect time to sneak back in and try to nab a quick nap before waking up with the team first thing. Usually someone's alarm would sound before the nightmares hit, so it worked out about half the time. But Jocelyn or Amane had probably locked it up before sleeping, and as Prism stared through the window, she could see her keycard taunting her from it's place on her desk. Prism raises her hand to knock, but glancing in reveals the utterly comatose state of her teammates, she - she - She can't bring herself to wake them up.
Looks like she was locked out for the night, but that's not terribly unusual.
With a sigh, another light breeze kicked up, and Prism soars up to the roof of the building. Landing on the flat top of the dorm, Prism settles down with a light "thump", before sitting on the roof. Setting the drawstring bag on her shoulder next to her, she digs through it to withdraw a worn scroll and a pair of earbuds, popping one in before digging once again for a bag of grapes and laying back. She might as well enjoy her time outside - it was a nice enough night, mostly cloudless with the broken moon shining high above.
Time to wait it out 'till morning.
