'Grey's Anatomy': 'Fresh Prince' Father James Avery Plays Man Who Loses His Partner (VIDEO)

Philip Banks was a devoted father and a good uncle to Will Smith on "The Fresh Prince of Bel-Air" two decades ago. James Avery, who brought Uncle Phil to such vibrant life, took on an entirely different role this week on "Grey's Anatomy" (Thu., 9 p.m. ET on ABC) playing an older man faced with losing his long-time partner.

In an emotionally packed farewell speech to him, Avery's character said that it had never been a fear of commitment that saw him wait so long to admit he loved him. "I was scared of this," he said. "Scared of how much I loved you. Scared of the feeling that I would never be able to find happiness without you."

All this talk of love finally got to be too much for Cristina, who stepped out of the room. Unfortunately for Emily, she stepped out as well to see if she could offer any consolation, and Cristina told her she could stop sleeping with her husband. Funny thing about that. Emily wasn't, though she did admit to some innocent flirting.

Owen did later admit that he was being unfaithful, but poor Emily hadn't deserved the long weeks of scorn she'd received from Cristina. But while Emily is off the hook -- does this mean the end of Summer Glau's guest run on the show -- Cristina and Owen are standing at a precipice in their relationship. How do they move on from here?

Find out as "Grey's Anatomy" continues Thursdays at 9 p.m. ET on ABC.
