Actor John Lithgow will be revisiting his role as the Trinity Killer in the upcoming Dexter revival season, according to Deadline. It’s also being reported that Lithgow will “only film for about a day or so,” which, if true, indicates the character’s return will not command a sizable amount of screen time.

Even if that proves to be the case, regardless, it’s safe to assume Trinity Killer’s presence will be pretty impactful in the next batch of episodes. In the show’s previous run, Lithgow’s character loomed as a revered, feared, and twisted father figure for the titular character’s serial killer trying to make peace with his demons. Deadline is also reporting Lithgow’s filming will take place next week, which means it’s reasonable for further details–including, for example, a longer shoot than initially reported–to come out after the fact.
