Gizzie sucks! MerDer are the only chemistry couple of this show. Boring??!! Great! They are always perfect with an amazing chemistry!


okie...i am a big Gizzie fan but it seems tht the writers have a different plan for them. i actually fell in love wit Gizzie in season 3 ep19 when they were in the closet together! Loved tht and the evelator scene! So much chemistry and love there! But i am now wondering what is happening?! the writers are killing the Gizzie story! Which sucks. cause i love them as a couple and seeing as though their love wasn't real seems so harsh! I get the whole forbidden love thing, but i dun think Izzie and George are so blinded and shallow tht they didn't realize it earlier. i mean...george left his wife for Izzie!! it has to mean something huge! they both clearly Love each other its just tht now, they *the writers* want humor and tried this road! i really hope Gizzie fans will stick through.


I think its a lot the same as the 3 seasons before...
The whole mer/der thing... it sucks
I want to see more originel things! (sorry, my English sucks)


Why isnt it any article about ERIC BANE's 35th birthday?
He's a big part of the show, he deserves some gratulations on this great fansite


I think in this episode both Grey sisters showed some interesting growth. I like that Lexie stood up for herself, that she's starting to understand Mer a little better, and that she's still trying. For Mer, I don't find her selfish or mean at all. It's a sucky situation from her perspective; family has always meant bad things. Actually, she never had a family until her group of intern friends...and now Lexie. Mer has grown by realizing that she doesn't hate Lexie, just what Lexie represents...which is someone being chosen over her. She spent the entire episode trying not to care, but you can tell she does. At the end, Alex basically "chose" Mer over Lexie, which Mer realized and I think appreciated. And she does care, or she wouldn't have worried and sent Alex to take Lexie home. Alex also got to see a part of Lexie's life no one else knows, and one he totally understands. That will be interesting to see what happens there. Mostly I just wanted to comment about the Grey sisters. I think most posters everywhere are being too hard on Mer, but as someone in a eerily similar situation, it's not easy at all. Mer doesn't have the same supportive foundation Lexie grew up with, so wouldn't find the situation as simple to deal with as Lexie does. For Lexie, they are sisters. End of story. Which means they should have a sisterly relationship. For Meredith, she did NOT grow up with sisters (or any family really) and still has to learn what that means. She's just trying to protect herself from getting hurt again, but at the same time, pretending she doesn't care...when it's OBVIOUS that she does. The rest of the episode was fantastic! Love the Chief/Derek interactions...funny! Love Mark and Cristina and their talks about Hahn. Adore the Bailey of it all...LOVE her!! Gizzie...heehee. as Cristina said in season 1 "Bad sex. Sucks for you." :-)


I do love Izzie and George together but I think I can agree with both sides. They had the drunken one night stand and then because that sex was so good they started to think of why exactly it was so good. Part of the thrill was the tension building up to the sex but now there's nothing keeping them apart which was the whole basis of their "forbidden love" romance. I am starting to like Lexi and i really don't want to but the whole Thatcher thing was so heartwrenching!


i was always so surprised that there were so many "gizzie" fans here and thought this was the case amongst all americans..but then i went on the website of msn.com where they asked viewers' opinions and comments on the gizzie situation and on FOURTEEN pages i did not see one supportive comment..so i guess all pro gizzie fans have just gathered here..don't get me wrong, i believe everyone has the right to love whomever they want but i just hate gizzie from the bottom of my heart as they are not credible and even if they were , they lack chemistry, they don't care about callie and they are utterly boring!
all in all i agree with one person on msn.com who said that *izzie and george never loved eaqch other but just loved the idea of loving each other".that's one thing i can believe.


I have started quite liking Lexie though why she sticks around Mer after being constantly shunned is beyond me. I wish now Mer shows some effort. Alex and Lexie could work and found their last scenes quite poignant. Who knew I could actually like Alex after the whole Addison bit Merder really bore me now and I wanted to know what do the Merdrer shippers think abt them now? I just dont see any chemistry and even the actors looked bored in the bedroom scene. Gizzie should stop now. I was all for it last season (linen, hannah, elevator) but now esp after the awkward sex I just cannot fathom those two together. I hope they go back to being best friends like before. I have a feeling Sloan and Izzie may just hook up. Poor Izzie needs some action and I hope they dont go the Alex route. Loved Baily and the Chief hug and found Christina and Torres annoying!


This episode was decent. I thought seeing Callie grooving during surgery was awesome, and I really hope they find her a solid story line - maybe Joshua Jackson! I can't wait to see Dr. Bailey kick some booty as C.R. now. I'm confused of why they got rid of Addison if they were just going to bring another woman character the same age for good, you might as well keep the original character? I'm REALLY ready for Christina to show up Dr. Hahn - or work with her - or something. No major comments on Gizzie - whatever happens, happens. But how can George not be married already - divorce doesn't happen that fast. Love seeing more Alex time. I thought it was cool seeing Meredith and him have screen time together for something different.

Grey's Anatomy Quotes

When we say things like "people don't change" it drives scientist crazy because change is literally the only constant in all of science. Energy. Matter. It's always changing, morphing, merging, growing, dying. It's the way people try not to change that's unnatural. The way we cling to what things were instead of letting things be what they are. The way we cling to old memories instead of forming new ones. The way we insist on believing despite every scientific indication that anything in this lifetime is permanent. Change is constant. How we experience change that's up to us. It can feel like death or it can feel like a second chance at life. If we open our fingers, loosen our grips, go with it, it can feel like pure adrenaline. Like at any moment we can have another chance at life. Like at any moment, we can be born all over again.


Doesn't matter how tough we are, trauma always leaves a scar. It follows us home, it changes our lives, trauma messes everybody up, but maybe that's the point. All the pain and the fear and the crap. Maybe going through all of that is what keeps us moving forward. It's what pushes us. Maybe we have to get a little messed up, before we can step up.
