Once upon a night...
I promise, Gage is in there somewhere. Yes, once upon a night, Gage didn't want to go to bed. He was scared: scared of noises, scared of the closet door being open even a little bit, scared of the hall light not being on, scared of not having a parent in the living room which is about 10 steps away from his bed.... Just---scared.
So, he built this bunker of buddies and slept behind the wall of watchful eyes.
