Greys Anatomy's Izzie and Denny not a 'ghostmance'

In this image released by ABC, Katherine Heigl portrays Dr Izzie Stevens, left, and Jeffrey Dean Morgan portrays Denny Duquette in a scene from the series, "Grey's Anatomy."

Is there a ghost of a chance that the renewed relationship between live Izzie and dead Denny on "Grey's Anatomy" makes sense? Yes, according to ABC Entertainment President Stephen McPherson.

"In terms of the ghost stuff, it's not a ghost, which you will learn," McPherson told a meeting on Friday of the Television Critics Association.

"You will be surprised at how insightful and smart the story line" is for the characters and for the show's direction, McPherson said. But, he added, television viewers will be the judge.

At the end of the 2005-06 season, Dr. Izzie Stevens' (Katherine Heigl) short-lived engagement to Denny Duquette (Jeffrey Dean Morgan) ended with his death after heart transplant surgery. But he's been reappearing to her in encounters that have turned passionate.
