Last night's Grey's Anatomy certainly gave longtime fans plenty to talk - and reminisce - about. If you missed it, read our official review of "Heart-Shaped Box" and share your thoughts on Thursday's developments.

Next week, Teddy puts her husband's life in her peers' hands when he's rushed to the OR for surgery and she's called away on another case, while Meredith and Derek receive the long-awaited news about Zola.

Callie and Jackson come under fire when their patient experiences complications; and Meredith and Alex are involved in a life-threatening situation when they travel to a neighboring hospital.

Shaping up like a dark, serious episode tailor-made for November sweeps.
