Denny Coming Back for More "Grey's"

Jeffrey Dean Morgan, who appears on Grey's Anatomy as Denny, Izzie Stevens's soul mate, keeps popping up on the show unexpectedly.

And now, according to reliable sources, no one knows how long he'll be sticking around.

"Izzie's got a love story, and it's a big one," series creator Shonda Rhimes told TV Guide back in August, "one that I've been kicking around in my head for a bit, one that required me to take a huge leap of faith in myself, one that is so secret that I have not told anyone. Not the writers, not anyone."

EW.com reports that Morgan will be around for at least five more episodes, but that number could potentially be more. So the only thing to do is tune in to see what happens between Denny and Izzie in the future because nobody's leaking anything on the set of Grey's.
