A scary scene in a scary movie (1st ed.)

Rene, an obsessive-compulsive fourteen year old, smells his hands and wears a Batman cape when he's nervous.

If he picks up a face-down coin, moves a muscle when the time adds up to thirteen (7:42 is bad luck because 7 + 4 + 2 = 13), or washes his body parts in the wrong order, Rene or someone close to him will break a bone, contract a deadly virus, and/or die a slow and painful death like someone in a scary scene in scary movie.

Rene's new and only friend tutors him in the art of playing it cool, but that's not as easy as Gio makes it sound.
