Kaz definitely heard it. Someone was definitely in there. Sounded male, judging by the pitch of whatever that crap was he was humming. Sounded like something he should've recognized, but it sounded very off somehow. Fucker's going through my stuff! He heard a couple of thumps, and thoughts of guitars in cases being loaded onto a cart made him tense up. All right. Time to play the hero.
He cracked the door slightly, quietly trying to get a peek at the intruder. From behind he could see him. Dark brown skin, curly hair, check... he watched as the person picked up his clothing, then quietly pulled back into the bathroom. Going for my wallet, of course. Expect nothing less from someone like that. Steeling himself, he threw open the door and let out a mighty war cry, can of hairspray at the ready, lunging to tackle the intruder, his boxers still lying forgotten on the bathroom floor.
