While MerDer are busy dealing with adopting adorable baby Zola and Calzona are honeymooning, what will Owen (Kevin McKidd) and Cristina (Sandra Oh) be up to in the season finale of Grey's Anatomy? Well, it's not all puppies and rainbows for that couple, series creator Shonda Rhimes dishes. Evidently Cristina receives "some disturbing news" during the May 19th episode that brings to light all that relationship drama we've been hearing about.

"And how she and Owen handle that news will speak volumes about the future of their relationship," Shonda teases.

Hmm, might the disturbing news be that Cristina didn't land the Chief Resident spot when her very own hubby was the doc in charge of choosing? We're pretty sure getting picked for the job has been Cristina's destiny for the past seven seasons, so we can see how that would be potentially devastating to the relationship. Will Cristina be able to accept Owen's decision and move forward with her marriage or will the two suffer a falling out due to her cut-throat, hardcore surgical attitude?

Watch the season finale of Grey's Anatomy on May 19th to find out.
