Grey's Anatomy is getting back into the swing of things, and it looks like Season 10, Episode 15 ("Throwing It All Away") will be a good episode, at least based on the promo. Relationship drama, medical drama, and even some humor — everything you need from a good week at Grey Sloan Memorial.

So, what does the promo tell us about the episode? We've broken it down to see what it reveals.

1. A baby in a box. As we see at the beginning of the episode, Stephanie and Jo quite literally find a baby in a box in the dumpster. Obviously, caring for that kid will be one of the plots of the episode. Poor baby!

2. Cristina and Shane interact. We haven't seen much Cristina and Shane interaction recently, but they'll have at least one scene together next week, as we see at :03.

3. Someone wants his kidney back? At :09 a patient asks April and Owen if he can get his donated kidney back. Yep, just another day of wacky medical cases at Grey Sloan Memorial.

4. Leah causes Calzona drama? We thought that Callie and Arizona had moved on from the Leah thing, but maybe not. At :10 there's a shot of Leah and Arizona looking at each other through a glass window, and at :12 Callie complains, "Now I have to deal with your jealous ex girlfriend? I swear to god I can't take any more of this!" Sigh.
