Will Alex be forgiven for what he did to Meredith in the Grey’s Anatomy finale? Perhaps, but after selling her out that hard, redemption won't come quickly or easily.

“What he did was wrong,” Justin Chambers tells TV Line.

“It was really uncool. There’s nothing worse than a rat. The alcohol had a lot to do with it,” he adds. “That’s the only thing that’s making me go, ‘Okay, we all make mistakes. We do stupid things when we drink.’ But still, that’s a hard one to get past.”

As for Alex's future romantic prospects, Chambers says his alter ego is more hung up on the past. The woman for Dr. Karev, even now, remains Dr. Izzie Stevens.

“They were the real deal - as much as a real deal can be on Grey’s Anatomy. That was the love of his life,” adding that he “would love” to see his friend Katherine Heigl return to give their storyline closure. “She is so fun,” he says.

“She is one of the funnest people I have ever worked with. She really is a special gal. I would love to have her back. Maybe we will before the season ends.”

Her exit was strangely open-ended, as we know. Would you like to see Izzie return to Seattle, and if so, do you think she and Alex should end up together?

Elsewhere on the Grey's front, Michael Ausiello teases:

• Kevin McKidd will direct the coming season's sixth episode, but unlike his debut effort, Owen (the new chief of surgery) will appear frequently.
• Scott Foley's Henry will be around “a decent amount of time,” according to Shonda Rhimes. “We’d keep him around forever if we could.”
• Kim Raver says, on that note, that “We start out [the fall] where they’re really madly in love. They’re really very, very close right now. I definitely think for Teddy, Henry completes who she is and what she needs.”
