Law and order: svu question??????

I think it might be Stephanie March since Sharon Stone has signed on to portray new ADA, Jo Marlowe. I missed the last half hour of yesterday's SVU, so who knows, but, if it has anything to do with what happened in the episode Turmoil, Stephanie could be out.Okay, so, I believe Sharon is going to be on the last 4 episodes of the season airing in April. It should be interesting since apparently she shares a past with Stabler and has lots of secrets of her own. Also, I believe Benson has said that she has always thought Jo Marlowe to be a man, so when she meets her she is kinda taken aback. I think it was speculated that they were suppose to have some kind of rivalry going on. Now, if it has anything to do with Marlowe's past with Stabler, that's still pending and entertaining the idea of that happening is pretty fun.
