The preview of "Grey's Anatomy" episode 5.04, "Brave New World", has arrived. After deciding to live together under one roof, McDreamy has to cope up with the fact that he won't be alone with Meredith in the house.
After lying naked in bed, waiting for Meredith to come home, Derek opens the door to find out Izzy, one of the room mates, standing in front. Teasing him with "Love the outfit", Izzy makes fun of Derek covering his modesty only with a pillow. This makes Derek giving an ultimatum to Meredith on how they should make the living arrangements. He wants Izzy and Alex out of the house.
Meanwhile, the official synopsis coming from ABC is read, "Meredith freaks out when Derek discovers her mother's old diary in the house, Callie frets as she prepares for her first official date with Erica, and Cristina stumbles into a part of the hospital that neither she nor her fellow residents have seen before."
"Brave New World" will be aired on October 16 at 9/8c.
