Since Denny clearly passed away back in May, it seems safe to assume that he'll appear in either a dream sequence or a newly created flashback.
TV Guide offers a few humorous options:
- Kenny. Denny's long-lost (and evil) twin. Just as Izzie is starting to feel get over Denny, her ill-fated soul mate's brother shows up to reclaim the $8.7 million inheritance!
- Ghost of Denny. At the opening ceremonies of the Denny Duquette Memorial Clinic, his spirit appears just in time to cut the ribbon. Poignant.
- An Alien. Okay, so this isn't the X-Files. But some of you may recall that while guest starring as Izzie's love, Jeffrey Dean Morgan was also a regular on the WB series Supernatural. Katherine Heigl, for her part, once starred on Roswell. Think about it.
Can you think of any other possible scenarios - serious or crazy - that may bring our beloved Jeffrey Dean Morgan back to Grey's Anatomy? Leave us a comment and share.
