It's hard to blame Dempsey for sounding a little weary of life at Seattle Grace Hospital. He spent last year in the thick of the off-screen dustup involving Grey's costars Isaiah Washington and T.R. Knight, while his on-screen duties have become a little repetitive. ''I'd like to see him marry Meredith,'' Dempsey says of Dr. Shepherd's romance with the will-o'-the-wisp resident played by Ellen Pompeo. ''All the relationships on the show are deeply flawed, but I think there should be a healthy one to be found somewhere.''
