Another strong episode -- and certainly a lot to talk about as a result! The Insider has put together its comprehensive Episode Guide to "What I Am," which you can read by following the link.

We would love to hear what you think about it, too. Post your thoughts and chat it up with fellow fans in our OFFICIAL FORUM.

This is your chance to tell the world how you feel about Denny coming back... Denny Sr., that is. Or what you thought of Mark Sloan's tumultuous first day on the job, George's breakup with Callie, and Meredith finally choosing between Derek and Finn.

All in all, there's certainly no shortage of material to discuss and we hope you'll share all your opinions and comments with us.

We're busy compiling our directories of quotes, pictures and music from the episode, and will continue updating each throughout the day. If you can find any of the hard-to-find song lyrics we're missing please contact us!

We'll also announce our weekly Caption Contest winner and post our staff Round Table discussion today. Check back with the Insider often!
