Spoiler Alert! 'Grey's Anatomy' Delivers a Surprising Night of Weddings and Babies


The big day finally arrived for Callie (Sara Ramirez) and Arizona (Jessica Capshaw), but their moment in the spotlight was soon overshadowed by a surprise wedding that no one saw coming.

It was a night of plot twists to leave even the most adept "Grey's Anatomy" watcher feeling a little dizzy.

Callie and Arizona worked out their pre-marital kinks and were well on their way towards walking down the aisle as Meredith (Ellen Pompeo) and Derek (Patrick Dempsey)simultaneously (and shockingly) opted for a quickie marriage license at the courthouse. It's not exactly the Mer/Der wedding we've been waiting for, but the two took the next step as a necessary action toward adopting an African orphan under Derek's care.

Watch the clip to catch up on last night's biggest happenings, and don't miss "Grey's Anatomy" when it airs Thursday nights on ABC.
