OnlyOnAOL: 'Grey's' season finale: Get ready for 'jaws on the ground,' says Jason George

By: Donna Freydkin

Poor Ben. He's had a rough ride over at Grey Sloan Memorial Hospital. Jason George, who plays the beleaguered trainee surgeon on the ABC medical hit "Grey's Anatomy," gave us the scoop on the season 12 finale that airs Thursday. Here are five things you need to know.

1. The finale will literally blow your socks off, promises George. And each character gets his or her moment. "It's a great episode. I was a fan before I was ever on the show," he says. "The table read is where we get to be fans. And then we have to go to work. There was laughter and tears and jaws on the ground."

2. We do know that he's married to chief of surgery Miranda Bailey (Chandra Wilson) and they're having some problems. His character got benched for performing unsupervised surgery, and his transition from anesthesiology is in question. "He's gotten in trouble once or twice, so far. Ben is confident as a doctor, but the question is, does he have the skills as a surgeon to back it up?" wonders George.

3. Ben moved from UCLA to Seattle to be close to his family. George, married with three kids, is also a family man. He's witty and personable, and has no airs or graces.He rolls with zero entourage, by choice, because that's his style. "When I do have people, it's one person," he says.

4. Like his character Ben, George is indefatigable and tenacious. He fights for what he believes in, and doesn't back down. "He doesn't know the word 'quit.' That's in me, too – this determination," says George.

5. Creator, producer and writer Shonda Rhimes vetted him before hiring him, to make sure he was a serious person and a proper grown-up. Meaning, no drama and no outbursts at work. "It's the greatest set," says George. "They have a no (expletive) policy. She and Ellen (Pompeo) create that."
