With all the drama surrounding Katherine Heigl's departure from Grey's Anatomy, many fans are wondering if anyone else wants off the show after the current season.

Well, you can at least bank on McDreamy sticking around for Season 7, according to Patrick Dempsey himself: "Don't worry, I'm not going anywhere," he told E! News.

Everyone can now breathe a sigh of relief!

As for Katherine, by all accounts she will be leaving Grey's for good. Details are still being hammered out, but we'd be surprised to see her again. Is that a good thing?

From what we're hearing, Justin Chambers (Alex) will be around as well, and you can expect an Alex-centric episode in the coming weeks, as his brother will be visiting.

Alex's troubled family history will soon come to light.

When said little bro shows up in need of pro bono surgery, pieces of Alex's past begin to surface, such as the fact that his family hasn't heard from him in some time.

As in, since he arrived at the hospital.

Interestingly that with all the people vanishing (Burke, O'Malley, Hahn and now Stevens), Alex Karev appears to have done the opposite, disappearing to Seattle Grace.

Lastly, there's a Grey's Anatomy-Private Practice crossover of sorts in the mix when Derek's little sister shows up at Oceanside Wellness to assist in an important case.

Derek has no plans to visit L.A. yet, but it's just a matter of time, you have to figure. Why have her cast as Derek's sister specifically if it weren't? Should be interesting!
