'Grey's Anatomy' spoilers: Callie's big news, Derek's choice and more

Note: This video will expire on Jan. 7.

"Grey's Anatomy" doesn't come back with a new episode until Jan. 6. So, if like us, you're missing the drama of Seattle Grace Mercy West, then why don't we do a little spoiler chat while we wait?

Déjà shoot: After all the controversy of last season's crazed gunman, the show is going there again. In the next episode, patients spill into the hospital after a gunman targets a local university. Will the crew be able to manage their deep fears during the crisis? Does Yang ( Sandra Oh) find her way back to practicing medicine?

Callie's big news: In the next episode, Arizona ( Jessica Capshaw) doesn't get a kind welcome from Callie ( Sara Ramirez) after her surprise return from Africa. That's to be expected. But, ABC's description for the Jan. 13 episode is creating a little buzz around Callie. It reads, "Arizona seeks Mark's advice as she tries to reconcile with Callie, who has big news of her own." 

Big news of her own? We all remember that Mark ( Eric Dane) and Callie partook in some rebound bump and grind. Could a baby be on the way? It would definitely increase the bond between the two, who have both had some parental urges in the last season. Arizona, a pediatric doctor, though, was not too fond of bringing her work home. Could this mean Arizona may be permanently shut out?

Meredith and Derek's rift: Also, TVGuide.com  reports that Derek ( Patrick Dempsey) will soon begin his Alzheimer trials, but he's still keeping Meredith ( Ellen Pompeo) on the outside looking in. When he decides to choose another researcher, big Grey goes big cray.

Teddy wedded: It's clear from the clip that Teddy  ( Kim Raver goes through with marrying Henry (guest star Scott Foley), so he can get health insurance. Do you trust him?
