Not too long! After a decently short go, he's coming back out in a set of PJs and going up those stairs. Give it an hour, hour and a half more, and the boy is out like a light.

It's really the upstairs that has most of the personal belongings too. A strange dragon scale, most notably, and...is that a sacrum bone? ...An acid worn sacrum bone? Don't worry about it.

Either way the kid (much like a certain someone) could use some hobbies, and hopefully he'll figure them out.

....and hopefully Pucci can find his own way in this place.
