Corrected entry: Episode 21, Season 3: Cirque des Merveilles. When Jesse is woken up in the middle of the night, he goes into the main hall of Sanctuary and is shirtless. He has no visible marks from being shot and operated on only 3 episodes earlier.
Mutant X (2001)
1 corrected entry in show generally
Starring: John Shea, Victor Webster, Victoria Pratt, Forbes March
Visible crew/equipment: At the dance club when Caleb Mathias holds Emma, Brennan comes to the rescue with a few swift airborne kicks. During one particularly high kick, the lines attached to Brennan are in perfect view above him.
Emma: I grew up in Seattle, I can't believe I'm praying for rain.
Question: Why doesn't Eckhart like people touching him?
Correction: We don't know how much time has passed between episodes. It could have been weeks or months and therefore the wound would have healed.
