Season 12 of ABC's "Grey's Anatomy" will come to an end May 19 and viewers can expect a "jaw-dropping" episode, according to actor Jason George.

Without revealing what's in store for the doctors at Grey Sloan Memorial Hospital, George who plays Ben on the medical drama, told Movie Fone that the show will shock fans when it finally winds up the season. "The thing is, I think the tone is ... it's going to end with ... there'll still be some jaw-dropping stuff in the finale. It's 'Grey's,' at the end of the day. There's going to be some fun light stuff, but it'll still, at the end of the day, we're going to end with some jaws on the floor," George said.

It is not immediately known what goes down in the finale, but fans can expect some sort of a tragedy, as "Grey's Anatomy" is known for its explosive finales.

Meanwhile, this Thursday's episode will see George's character Ben landing in trouble after he once again fails to follow protocol. According to the summary of "There's a Fine, Fine Line," Ben will operate on a pregnant woman without proper surgical equipment. This will land him in trouble with Bailey [Chandra Wilson], who is not only his wife, but also his boss' boss. She will be forced to set up an advisory committee to decide what disciplinary action should be meted out to her husband.

Previewing what's in store for his character, George said things are going to get hectic for Ben, who is an experienced doctor, but a new surgeon. "So you can think more of your skills than you might have, or you might be making the right choice," he told Movie Fone. "It creates this place where maybe he did the right thing, but they think he did the wrong thing. Or he did the wrong thing, but he thinks he did the right thing," George said, adding that things are going to reach an explosive level and his relationship with Bailey will be strained.

"Grey's Anatomy" airs Thursdays on ABC.
