Look at the picture of Alex/Izzy; SMILING! Eeeee!

I am so pissed at Meredith right now. So pissed. George is not a rebound guy! He's better than that!

pissed pissed pissed!

McSteamy Heat

On ''Grey's Anatomy,'' Addison's partner in adultery visits to try to win her back; meanwhile, George makes his big move on Meredith by Tim Stack

Is it hot on Grey's Anatomy, or is it just me? It's true that I've been illin' like a villain for the past couple of days, fighting off a wicked sinus infection, but Grey's definitely upped the sex ante this week. (My illness is going to keep things a bit brief this time, but I'll still try and hit all the high points of the episode.)

First, I'd like to see more dancing on Grey's Anatomy. Cristina and Burke's little opening dance-off was fantastic. This is where ER gets it wrong: Medical dramas can always use a good rump shaking. It offsets all the sickness and dying. And bomb threats.

Second, we were introduced to McSteamy (Eric Dane), McDreamy's former best friend and the man Addison had an affair with. McSteamy is exactly what his nickname suggests: hot. Now, that shouldn't necessarily be a prerequisite for employment, but if I were running this hospital, I'd snatch him up right quick. Even with stitches in his face, the man looks good. Patrick Dempsey, you officially have competition.

Third, a woman was brought into the ER experiencing spontaneous orgasms. While I'm still a little shocked they could show her, um, reactions on network television, I have to say this story line was amusing. Plus, in true Grey's fashion, the story started out somewhat over-the-top but eventually felt quite moving and real.

Fourth, George (T.R. Knight) and Meredith are going to do the deed! Well, at least that's how it appears from what was hinted at this week and apparently confirmed in next week's preview. All we saw was George profess his love for Meredith (''I would never leave you. I would never hurt you. And I will never stop loving you.'') and then Meredith helped him remove his shirt. Damn you, Grey's Anatomy and your amazing cliff-hangers! That being said, it was a great moment, but I'm not sure how I feel about the two of them getting together. It's a little Ross and Rachel.

All this and Meredith saw her father for the first time in 20 years!

What did you think? Are you for or against George and Meredith hooking up? Do you wish Izzie and Alex would stop feeding the beast? And who's hotter: McDreamy or McSteamy?

im still pissed

I like George...but not after that...but she was just as much to blame cause she was vulnerable about the whole thing with her dad...but the whole thing is just NO! Just so digging how they did it.

ANd about Eric Dane...yeah, I read this article where Rebecca said how much he helped her out after the car accident.

I agree completely. I kind of said it in next week's episodes thread, but come on. He knew she was upset. He knew she didn't care about him like that...she blew him off. He told Izzie that. He knows she doesn't love him. He knows she's in love with McDreamy. Come on!

Meredith...love her, but this was a bit low even for her. Very bad! So, let me get this right...when I'm really upset about something, I should go sleep with some guy...the closest guy will do? Nice! First McDreamy, then the guy that couldn't get rid of his erection, and now George. And she had the nerve to call her mom a whore...guess the apple doesn't fall far from the tree, huh?

I'm kind of disappointed with both of them.

I just read the writer's blog for the first time. Very cool.

But I still think it was stupid!

I'm never gonna forgive George. Ever. He will be forever enshrined on the Hannah hate list along with Lauren, BA and JJ Abrams. LOL
