what are your reactions about Lexie Grey?

I thought that she was around 9 or 10 when he left Meredith's mom. Maybe not? I think including Lexie in the show adds a new plot twist. I thought it was interesting that it was her Derek was flirting with in the bar. Wouldn't it be ironic if her and Meredith break up and he ends up with Lexie? Actually, I hope Meredith and Derek get things worked out. I like them as a couple.

No, because you don't know what age they both were when they started their internship. Meredith might have started it at an later age than lexie. I think it will be interesting to see how lexie fits into everything there.

So is this Lexie another sister other than the one that was in the hospital? I thought it was just a coincidence that their last names were the same. I really hope Derrick and Meredith work it out but I don't see it happening as Cristina is going to need a lot right now and, like Derrick said, sha is always there for her friends.

I don't like this Lexi girl already. LOL. But it really just depends on how they unfold her character, I remember loathing Addison at first but now she's my absolute favorite and wish she wasn't leaving GA, but I'll watch her show. McDreamy will probably start seeing Lexi, and Meredith will probably get jealous of him b3int with not just another woman, but her half sister, and will want him back. I'm not very impressed with the way things are turning, I hope season 4 is a lot better than it looks like right now.
