S1·E4 Episode 104

Thom encounters Damian in Jonathan's hospital room, instantly reminding Damian of Richard Devere, the man who painted his portrait two centuries ago, the only man he's ever loved. Devere was a vampire who gave Damian immortality and the capacity for evil; Damian in return drove a stake through his heart. He believes Thom to be Devere reincarnated, and Colin takes advantage of Damian’s infatuation to finally gain control of The Lair.
