When it was first announced that Neve Campbell would play one of Derek’s (Patrick Dempsey) four sisters on an upcoming episode of Grey's Anatomy, we went through what we know about each sister, and tried to figure out which one Neve would be.

Now, thanks to an ABC press release, we know the answer. But it actually leaves us with more questions than before.

Now we know that Neve Campbell will be playing Liz Shepherd, the one Shepherd sister who we know absolutely nothing about. Which means that her storyline, and her reasons for showing up in Seattle, are completely open-ended. She could be another doctor, a mother with nieces and nephews for MerDer, or a fugitive. The possibilities are endless!

One thing’s for sure: Neve will make her debut in Season 9, Episode 8: “Love Turns You Upside Down”, airing December 6. We’ll be watching!
