Grey's and the Grey Area(s)

I love Grey's....I'm a faithful supporter of the show (thanks Brew).  I've been addicted for the past few seasons and if you call me on Thursday night you will be chatting with my voicemail.

With that being said....How in the hell did they come up with this plot line with Denny and Izzy?

Umm...He's dead....they have sex...she's imagining him....HUH??? Ok so sidenote: I love Denny...I welcome any chance to look at him, but the plot is so WEIRD.

And how in the world can you justify sex with a dead man that you are imagining but the lesbian couple was written out because the story line didn't flow?  

Ok I didn't like Erica Hahn, but at least their relationship made sense.

(Sigh) I'm done.
