Are Mark and Lexie over for good on Grey's Anatomy? Yes? No? Maybe?

To hear Chyler Leigh tell it ... we're still not sure. But the actress did open up about the subject along with other Grey's Anatomy topics in a chat with TV Line.

Some excerpts from her talk with Matt Webb Mitovich appear below:

On whether Lexie is really digging Jackson or just using him as a distraction from Mark: "Well, it’s a complicated situation. As far as Jackson goes, they have so many similarities ... They’re both very driven, they’re both up-and-coming in their careers."

"They’re into the same things, and there’s something that’s really refreshing about that for her. He obviously really cares about her, and she really cares about him, so there’s that blossoming of something new. But yeah, there is a distraction [element to it]."

On who needs to grow up, Lexie or Mark: "I say Mark, but you know - whatever!"

On Lexie's reaction when Mark stepped aside: "I was very careful in the way that I chose to play that, because I didn’t want there to be too much of her searching him, saying, 'No, tell me to stay!' She had to make a decision for herself."

“[She had to say], You know what, this isn’t where I’m at. I’m with somebody who makes me happy, and who I can see some sort of a future with and still be able to focus on my career and not have to worry about being some step-mom.”

On the season ahead, which may be the last for some original stars: "The great thing about the show in general is that it has so much legroom to continue to grow. You can continually bring in new characters, so it’s an ER situation in a sense."

"There’s always someone coming in, the prospect of interns, the residents now having interns, which we really haven’t gotten to see yet ... There’s a lot of room for new storylines and growth. I can represent the Grey [in Grey's Anatomy], I’m not going anywhere!"
