After a tumultuous week of news surrounding the departure of Erica Hahn (Brooke Smith), the drama will play out in one way or another on Grey's Anatomy tonight at 9 p.m.

In "Rise Up," Izzie has a shocking realization as the patient she stole Denny's heart from returns. Hahn is upset - and supposedly Denny makes another appearance as well.

Elsewhere, Derek turns to an unusual source for advice - Bailey - when Cristina interferes with his and Meredith, and the residents fight tooth and nail for a big solo surgery.

You can discuss it before, during and after the show in the Insider's photos, as well as the videos and quotes we've assembled from this episode so far. We'll add more after the episode airs.

We also post our recap along with a music guide, Round Table and more!

Thanks you all for watching Grey's Anatomy along with the Insider!
