Everything is at stake this week on Grey’s Anatomy season 11, episode 8, “Risk.” Get a preview with the stills and synopsis!

Meredith and Derek seem to be hanging by a thread on Grey’s Anatomy. Especially after he almost stole his sister’s job last week. This week, it will be Meredith on Maggie’s side. Derek wants to a treat a patient his way while the sisters have their own idea.

That won’t be the only thing in danger during the winter finale. When Stephanie gives April an ultrasound she sees something worrying. She’s not sure what do about it – given that Jackson is her ex. Here’s to hoping that it’s just Stephanie’s inexperience and that baby Avery is just fine!

Plus, Amelia will work to bring back her good name at the hospital. Starting with Owen! Amelia will approach the Chief of Surgery to talk about her sobriety. And Owen’s response will leave Amelia surprised.
