Mason

Mason is a character in the Claire's Impossibilities series. He is described as "the gentleman" in Soulless.

Impossibilities
Mason, a Magic: the Gathering player, finds Claire at the high school's upper parking lot during the fire evacuation. He most likely died when Claire caused a Ford Fusion to spontaneously combust, though he was brought back to life when Claire's writer reset the world.

Soulless
Mason is present when Nathan smashes Claire's flashlight into Claire's face and gives her Soul-sight. He helps Claire to the nurse's office after lunch.
