A solution for the hospital. April (Sarah Drew) is all about emergency care, and last week Derek (Patrick Dempsey) was the most distressed of anyone when Dr. Cahill explained her proposal to shut down the ER. So it's no surprise that, according to the official synopsis of the episode, those two docs will spend the episode working "around the clock to find a solution for the hospital."

Cristina's medical dilemma. This week, Cristina (Sandra Oh) will struggle "to respect the wishes of a family whose son is dying." Based on the preview of the episode, it looks like the family will ask to decline some sort of medical care in favor of prayer.

Arizona empathizes. Meanwhile, Arizona (Jessica Capshaw) "empathizes with a teenager who faces problems similar to her own." We're guessing the teen will also have a missing limb of some sort, or perhaps s/he will have trouble walking for another reason. 

Meredith in trouble? The preview for the episode also shows Meredith (Ellen Pompeo) clutching her stomach and saying "something's wrong." Is there a problem with the baby?
