Hisoka turned quite red himself when the others noticed him, quickly ducking back into his room, pulling the towel tighter around his waist, though he kept the door open long enough to stammer out a quick "Sorry!" to the girls, cursing himself under his breath for not having gotten dressed before going to investigate the noise. Sighing, he went to sit on the bed, laying back... and just falling asleep right their on top of the covers, exhausted from the odd day.
