Sandra Oh's departure won't be the only focus of the season 10 finale of Grey's Anatomy. Turns out, there will be a lot more the doctors will have to deal with.

The Grey Sloan Memorial staff will also have to treat "a number of victims injured during a possible act of terrorism," according to TVGuide.com. Talk about some serious drama, right?

It's unclear how this will tie into the goodbye of Oh's character, Dr. Cristina Yang, which will presumably be very emotional. Not too many details have been released in regards to Oh's send-off, but we do know that Isaiah Washington will reprise his role as Dr. Preston Burke to help wrap up her storyline.

"I read the script last night," Washington recently told Access Hollywood Live. "The script is so amazing... it will blow you away... I was not expecting this."

The show creator Shonda Rhimes explained the decision to bring the actor back via a statement, saying, "Burke is vital to that journey - he gives her story that full-circle moment we need to properly say goodbye to our beloved Cristina Yang."
