Last week, we talked about the glorious and perplexing news, courtesy of Michael Ausiello at TV Guide, that Jeffrey Dean Morgan will be reprising his role of Denny Duquette on Grey's Anatomy.

Now, Kristin Veitch of E! Online has more on how Denny Duquette comes back to Grey's, and shares with us a few juicy details of his return.

Inside sources reveal the following pieces of information, which should put to rest some speculation while fueling even more:

1. Denny does not appear in a flashback.
2. Denny does not appear in a dream.
3. It is Denny and not something kooky like his twin.
4. Denny is not the only one we see.
5. And for the record, the scene in which Denny appears will completely blow your mind.

Wow. That's a lot to take in.

Needless to say, cancel any plans you might have for the next few Thursdays and make sure you check out what happens with our friends at Seattle Grace. Because everyone will be talking about the next few episodes of Grey's Anatomy. Apparently, "Walk On Water" was only the beginning.
