I agree with a fluid cast for a show that's been on so long and especially when it means you can eventually get rid of people like Serena (worst assistant DA ever?), but NOOOO NOT JESSE L. MARTIN! HE'S AN INSTITUTION! HE'S MY ANCHOR! HE WAS LENNIE'S PARTNER :(

I mean, unless it's only for a few months so he can do Rent again, I think it's in the Constitution that he can't play any other character.
