Commonality is Comfort (right?)

Denver lives self sufficiently, as a result of parental neglect. He fends for himself, and to make things easier he has fallen into a very specific rhythm of life. His walls are full of pictures; you can't even see behind them at all. This is the only thing he let's be 'out of line.' Art is a strange thing. Most say it speaks to the eye of the beholder, but this art speaks to itself. And to Denver. One day, his routine it broken by a new kid at school: Elton. He is... very attractive to Denver.

His routine has been thrown off.

They become friends, and find something rather queer in his grandmothers house.

Dead or alive?
