What did you think of tonight's episode? As usual, this hardly a shortage of topics worth discussing. The Insider has put together its comprehensive Episode Guide to "Oh, The Guilt," which you can read by following the link.

We'd love to hear what you think about it, so please post your thoughts in our OFFICIAL FORUM and talk about whatever strikes you.

This is your chance to tell the world how you feel about Izzie's decision to come back, Burke's ongoing battle, Bailey's maternal instincts, Mer/Der, Der/Addison, Addison/Mark, Mark/Callie, Callie/George... you get the idea. Discuss!

All in all, it was another good episode, and we're grateful for your visit to our site. We hope you'll take this opportunity to share all your opinions and comments with us and fellow fans.

On our end, we're busy pulling together our pages of quotes, pictures and music from the episode, and will continue to update each as we acquire the data. We'll also announce our weekly Caption Contest winner and post our staff Round Table discussion Friday. Check back with us often! Enjoy!
