Grey's Anatomy Season 10 Spoilers: Calzona Repaired, Jolex In Trouble?

After what seems to be an entire season of Calzona hate and war, it seems Callie Torres (Sara Ramirez) and Arizona Robbins (Jessica Capshaw) have finally - and truly - reconciled. In Grey's Anatomy Season 10, Episode 11, "Man on the Moon," the couple has finally started "talking less" to really repair their marriage. Now fans of Arizona/Jessica couldn't wait to see the lovely actress in a beautiful gown and hairstyle again.

On the Jolex front, Jo Wilson (Camilla Luddington) is still trying to help Alex's dad Jimmy (James Remar, "Dexter"). Alex Karev (Justin Chambers) has warned her, but she is committed to being a professional. And it seems she really does want to heal both the father and son. Will the three figure in some shocking, gut-wrenching mid-season finale ending?

"There are multiple pieces to the cliffhanger. We're hopping around during the last minute all over the place to the point that when we were reading it during the table read, Ellen Pompeo stopped the table read and was like, 'What?! What is happening? Are you kidding me?'" Sara Drew teased fans via TV Guide. What made Ellen Pompeo react that way - Cristina Yang (Sandra Oh) or Derek Shepherd (Patrick Dempsey)?

"It's not just April's wedding that is wrapped up into that last five minutes. We come back from the break with a hell of a lot of tension," Drew added. Fans should not miss Grey's Anatomy Season 10, Episode 12. Who should "get up, stand up?" When Shonda Rhimes or the Grey's actors hint something big is happening, they are usually right. Will someone die in this episode? Death and Shonda Rhimes' plots are never far away from each other.
