Grey's Anatomy fans will recall the exciting news that Neve Campbell will soon appear as Derek’s (Patrick Dempsey) sister on an upcoming episode, and now we know which one that is: Season 9, Episode 8: “Love Turns You Upside Down,” airing December 6. So what else happens on that episode?

ABC has released the episode info, and it sounds like this episode will be focused on the interns. But that doesn’t mean that our favorite doctors aren’t in the mix. According to the press release, “The new batch of interns find themselves involved in all the drama at Seattle Grace.”

What that means for Meredith (Ellen Pompeo) and Derek is that “Meredith asks Heather to go above and beyond to help fix Derek’s hand.” We wonder if that means Heather (Tina Majorino) will be working alongside Callie (Sara Ramirez) as well.

The proudly mean Cristina (Sandra Oh) will actually have a counterintuitive storyline: “Cristina starts a healthy competition between Stephanie [Jerrika Hinton] and Leah [Tessa Ferrer], which inadvertently leads to a medical emergency for Cristina’s patient.” Cristina losing control of her patient? That’s something we’re not used to seeing.

Also in the episode, “Alex [Justin Chambers] sees Jo [Camilla Luddington] in a new light as they work to save a baby’s life, and April [Sarah Drew] teaches Shane [Gaius Charles] a valuable lesson during ‘lumps and bumps’ duty.” We can’t help but wonder if Alex and Jo have a romantic relationship in the future.
