Another Thursday night with no new Grey's Anatomy. Sigh. Well, at least we will be treated to a repeat of "What I Am." This was certainly a good one, marked by the mysterious arrival of Denny Duquette (Sr.) and numerous compelling plot lines involving our favorite surgeons, including the lingering self-doubts of Drs. Burke and Yang and the resolution of the love triangle between Meredith, Derek and Finn. It will be great to watch... again.
