Chyler Leigh discusses 'Grey's' finale

Chyler Leigh has assured Grey's Anatomy fans that the season five finale will be positive for Lexie and Mark.

Speaking to TV Guide, Leigh said that the final episode will end on a high note for the lovers.

"It is definitely good", she said. "She's got all of her ducks in a row as far as what she wants for her career. Now to have fallen into a relationship that she wasn't expecting, throws some of those plans off. It will be interesting to see what happens next season."

Discussing rumours that T.R. Knight is to depart the series as George, she said: "I know nothing, and it's still too early to say. We literally just wrapped.

"I haven't been told anything, and I'm not even sure T.R. knows, or even what's going on with Katie [Heigl] and all that stuff. I don't know if anybody knows what's going to happen."

The actress recently announced the birth of her third child.
