Ash (Supernatural)

Ash, portrayed by Chad Lindberg, is a mullet-wearing computer expert, who works and lives at Harvelle's Roadhouse with Jo and Ellen Harvelle. He attended MIT, but was kicked out for "fighting". He owns a homemade laptop, which he uses to track the paranormal, particularly Azazel, with the information John Winchester and his sons, Sam and Dean Winchester, have gathered. In the episode "All Hell Breaks Loose: Part 1", he calls Dean to tell him he has discovered something important, but by the time Dean arrives at the Roadhouse to talk, the Roadhouse has been burned to the ground, and Dean finds Ash's corpse (identified by his distinctive watch) in the rubble.

Series creator Eric Kripke stated that Ash's death "had to do with how much I hated the actual Roadhouse itself rather than anyone in it." As for the character's return, Kripke replied, "Ash is a possibility." This comes to fruition in the fifth-season episode "Dark Side of the Moon", in which Sam and Dean meet Ash in Heaven, as well as Pamela. Enjoying the afterlife more than his actual life, and having discovered means to infiltrate other people's Heavens and tap into the angel's communications, Ash helps the brothers hide from Zachariah. Ash also revealed to them that they've died more times than they know and he has helped them before, with the angels erasing their memories upon resurrection.
