Here's all the latest scoop from Michael Ausiello at TVGuide.com:

Will Alex and Addison "happen" before she leaves?

(Major spoiler alert) Remember how I told you that Grey's decided to put the brakes on Addisex due to Kate Walsh's impending spin-off-fueled exit from the show? Well, it appears either Shonda Rhimes had a change of heart or I was given some lousy intel, because the two of them are definitely doing the horizontal tango before she leaves for Los Angeles. In fact, I hear it's their little affair that ultimately leads her to flee Seattle. Also not helping matters: McSteamy's "failure" to stick to his 60-day vow of chastity. Why'd I put failure in quotes, you ask? 'Cause there's a twist (and a surprising one at that)!
Just saw your latest vodcast. Please tell me it is not Derek who slaps Meredith in the face.

And ruin all the suspense?! Pshaw. I can tell you that Derek and Meredith aren't exactly on solid footing by the end of the May 3 episode.
I just had two wisdom teeth pulled, so please pity me and give me some Grey's Anatomy scoop!

Addison won't be the only Seattle Grace doc who is considering a change of scenery in the coming weeks. My Grey's mole reports that all the drama surrounding Gizzie-gate will prompt George to consider transferring to another hospital.
