Warning: This article contains spoilers for Grey's Anatomy Season 9, Episode 2: “Remember the Time.” Stop reading if you don't want to know!

On Grey's Anatomy Season 9, Episode 1: "Going, Going, Gone" we sobbed through Mark's (Eric Dane) death. In that episode, we saw he'd been on a coma for a month. But at the beginning of Season 9, Episode 2, which flashed back to after the plane crash from Season 8, he was awake.

So, what happened?

It was "the surge." Mark arrived in the hospital barely hanging on to life, and the docs were sure he was on his way out. But then he had an apparently miraculous recovery, coming back to his chipper self.

But it turns out that was something called "the surge," when a patient on the edge of dying has a last surge of energy. They seem back to themselves, and take the time to say, essentially, goodbye, sharing the important things.

And that's what Mark did. He gave Jackson (Jesse Williams) a touching speech about doctoring and love. He rambled about Callie (Sara Ramirez) being amazing. He was, for one last episode, his old, glorious self.

Then he signed a living will specifying he wanted life sustaining care withdrawn after 30 days, slipped into a coma and the rest, as they say, is history. Sob.

Grey’s Anatomy airs Thursdays at 9 p.m. ET/PT on ABC.
