Grey’s Anatomy has promised a glorious show to their fans on their 100th episode. And why not? Their fans have been very supportive of the show from day one.

So what happened on the first part of 100th episode?

- We already know that Izzie has been suffering from cancer for quite some time now, and yet managed to “help” (or turn into nightmare) the wedding day of the couple who doesn’t seem to be into weddings.

- Denny appears again (but looking better this time… ) and Izzie gets into panick mode.

- Dr. Shepherd finally managed to locate the part of Izzie’s brain which causes hallucination.

- Everyone seems to “guard” the couple as the countdown to their wedding starts.

- Meredith and Derek decided to “give” (sorry, can’t think of a better verb) their wedding day to Izzie and Alex (I loved this part by the way, although most fans would have preferred Derek and Meredith to get married… c’mon, you know this couple… they hate anything conventional).

- Izzie loses her hair, while Alex assures her that she’s still hot (she is, actually, hair or no hair)

So there you go for the first part. I’ve been reading a lot of things that would happen next but I don’t want to discuss it yet until I watch the second part myself.
