Friendships are about to come under fire thanks to the law on Grey's Anatomy Season 10, Episode 16  ("We Gotta Get Out of This Place"). We'll see Callie (Sara Ramirez) and Derek Shepherd (Patrick) face off over their research, and we're already worried about the consequences.

What else can we expect from this episode? We've gathered all of the most interesting info and spoilers about it right here.

The Official Synopsis

Let's start with the official synopsis of the episode, which gives us a lot to chew on:

It's Richard's birthday and Bailey invites him to scrub in on the case of a lifetime. Meredith [Ellen Pompeo] hires a research assistant to help with her portal vein project, and a scorned Callie gives Derek [Patrick Dempsey] quite the shock. Meanwhile, Shane [Gaius Charles] helps screen candidates for Cristina's [Sandra Oh] clinical trial and meets a young expectant mother (Keke Palmer) who needs his help.

So Many New Faces!

As you can tell, there are a lot of new characters this week and that should be fun. Shane's teen patient is being played by award-winning actress Keke Palmer. Meanwhile, Meredith's research assistant is played by Greek star Paul James, and he could be sticking around for a longer stint.
