Word surfaced that the character of Arthur Mitchell, otherwise known as The Trinity Killer, would appear in Resurrection. And ...
John Lithgow will return to play the Trinity Killer in Dexter: Resurrection, and fans couldn't be happier about it.
Arthur 'Trinity' Mitchell's spin-off lacks Dexter's appeal due to his lack of redeeming qualities. The Trinity series aims to explore his origins but may struggle since Trinity is purely a villain.
Based on the limited knowledge available about the character and the extensive work of his actor, this new villain could even rival one of Dexter's best serial killers, the Trinity Killer.
John Lithgow apparently confirmed his return as Arthur Mitchell, aka "The Trinity Killer," for an appearance in Dexter: Resurrection.
