Four "Brave New World" Sneak Previews
This week on Grey's Anatomy, Derek (Patrick Dempsey) is officially moving with Meredith (Ellen Pompeo) and you know that's going to result in plenty of nakedness drama.
Case in point: The clip below from "Brave New World" ...
That's not all, though. Not only does McDreamy discover Ellis Grey's journal, but his presence in Meredith's house results in some major tension between her other roommates.
Elsewhere, George is fretting over whether he passed his test, and Callie is (awkwardly) prepping for her big date with Erica. Follow the jump for three more preview clips below!

October 15th, 2008 7:32 PM
hahahah Callie and Bailey
October 15th, 2008 8:40 PM
Bailey's face is priceless. Incredibly funny.
And to Meredith: SERIOUSLY?! Unless you plan to tie him to the bed so Derek will wait for you naked, stupid stupid woman. Hell, I'd tie him to the bed...pleasant thoughts :) that way, I don't kill Meredith.
Why would Derek bring up the diary anyway...bad timing.
October 15th, 2008 8:47 PM
hey meredith is the best!!!!
October 15th, 2008 9:04 PM
She is the best but at that moment...walking away from naked Derek...not cool. That's what I meant ;)

October 15th, 2008 10:38 PM
what does meredith say at the end after i have to shower?
October 15th, 2008 11:54 PM
So I will be honest, I originally wasn't too fond of the Callie/Erica relationship (because I loved Callie with Mark) but not I can't wait!!
October 16th, 2008 12:01 AM
I meant but now I can't wait!
October 16th, 2008 12:12 AM
I think she says "I have to um shower from hauling Cristina's boxes."
she was probably helping cristina move into that new apartment with the fireplace
October 16th, 2008 12:15 AM
okay...derek, if your going to do the whole naked in bed thing, HIDE the diary! i mean this is meredith!! she's not going to be okay with you being alone with her mom's diary!
October 16th, 2008 1:24 AM
Bailey...AWESOME!!! Callie with the whole south of the border and northern mountains ... I will be crying laughing during that scene XD
October 16th, 2008 2:06 AM
This meredith and derek thing is getting extremely boring. I mean, I know every relationship has its problems especially when its starting but this is ridiculous, every little thing seems to be a problem for them and we're stuck in the same thing. I bet you at the end of the episode they sort things out and are happy again. BORING
October 16th, 2008 6:23 AM
as much as i love them, guys, let's be serious...they can never truly be together..and get married and stuff..that will end all the show.
alex is beeing an ass again with izzie, which i hate...and poor george seems to be a little robot chasing after the chief to get an answer.
as for callie and erica...i'm not into erica. i liked sloan better
October 16th, 2008 7:21 AM
haha i know what u meant but still i would be mad if my bf went through my stuff and took my dead moms diary. shes just a little protective i guess??? shes like ''my person'' haha so i always stick up for her hahaha lol
October 16th, 2008 7:37 AM
hahahaha Bailey's face was hilarious!!! :D
October 16th, 2008 8:45 AM
Glad that Mer didn't go to extreams when Derek told her about the diary.....she just kinda said Oh. She stil has those issues with her mom. Love her!!!! Can't wait for all the Callie Bailey conversations.....especially the Vajay-jay speech I saw in a promo lol
October 16th, 2008 8:46 AM
Okay, i can't be the only one that hopes McSteamy will help Callie with the 'south-of-the-border' stuff. Her going to him for advice would be awesome. In my mind that is the funniest scene that could ever be written.
