'Grey's Anatomy': Neve Campbell Guests As Derek's Sister (VIDEO)

While the bulk of the episode focused on the new batch of interns, "Grey's Anatomy" brought in a big guest star to propel Derek's storyline forward. With a bold new plan to try and save his hand, his sisters were contacted to see if any of them would be willing to donate a nerve.

His sister, Liz (or Lizzie), agreed and so Neve Campbell showed up. She walked right into the middle of a fight between Brooks, Meredith and Derek. Brooks was tired of feeling like she was always in the middle, which Lizzie quickly diagnosed was a result of her parents' messy divorce.

She was clearly a take-charge woman, as she quickly moved on to making sure she got the most out of this visit with her brother. "Good to see you, Mer. I hope you’ve got some baby pictures handy, because I did not take the red eye just so my brother could hack my nerves into hamburger meat," she said.

That's right. Campbell is going to stick around at least until this surgery is complete, and sites like Buddy TV and Celebuzz are happy to have her.

"Grey's Anatomy" continues on Thursdays at 9 p.m. EST on ABC.
