Okay, now he’s really dead.

Jeffrey Dean Morgan confirms that he’ll reprise his role as Denny on Grey’s Anatomy before the end of the season. But then that’s it. Really.

“I can confirm that I will be coming back one more time,” he revealed to us at last night’s Hollywood premiere of Star Trek. “I think it will be done after that. I think I have been on the Grey’s Anatomy set for the last time.”

Morgan wouldn’t say when exactly Denny turns up, but I can confirm that he’ll reappear as a figment of Izzie’s

cancer-ravaged imagination in next Thursday’s wedding-themed 100th

episode. “Denny has a reason to show up,” Morgan teases, “and it is

probably tied to Izzie’s health.”

Given the number of times Denny has returned to Grey’s since

croaking three years ago, Morgan states the obvious when he says, “I

think they’re regretting killing me off a little bit. But it’s done and

it’s been great and I love those people. [Series creator] Shonda Rhimes

gave me the opportunity of a lifetime.”

What do you think brings Denny back next week? And will you be sad to see him go? Sound off below! (Reporting by Carrie Bell)
