Meredith and Derek bond with the baby, and name him Bailey. Meanwhile, Ben congratulates Bailey on the surgery. She’s desperate to find Richard – he’s unconscious in the wet electric room with sparks all around.
Amazing season finale with tons of tension and alarming developments! I never really thought Meredith would die, so that was a little anticlimactic, though still very dramatic. I most enjoyed April's fit over Jackson, and Alex finally telling Jo how he feels. Gah! Christina's conversation with Owen was refreshingly honest - a long time coming. I would like to see Owen become a father more than I want them to stay together. Most worried about Richard and Arizona and Callie - though I predict Richard will be okay and Calzona will work their way back together.
