Felicity does some more wandering. He takes his poof. He takes his poof's fountain, too.

An hour after Elspeth leaves, he goes back in the house. It takes a little time and ingenuity to set an empty cereal box on fire - he's already out of triangles anyway, and hasn't asked for more - but he manages it, and then he carries it around to as many flammable things as he can, and then he curls up on the living room floor and waits.
