We want to mine as much info as we can in preparation for the new episode, so we've taken a microscope to the promo to see what we can learn.

At a different hospital: It looks like the docs are taken to someplace closer by than Seattle Grace-Mercy West (possibly the Boise Hospital they were headed to). That means the people treating them — and the ones in charge — aren't the docs we know and love .
Meredith confused? We see Meredith (Ellen Pompeo) sitting up, either in a hospital bed or in a rescue vehicle, asking "my sister, where's my sister?" Has she forgotten what happened, or does she just want to make sure someone found Lexie's (Chyler Leigh) body?
Owen is there for Cristina: As see in this sneak peek, Owen (Kevin McKidd) will be there for a very traumatized Cristina (Sandra Oh), who is non-responsive when Mer begs "say something, please!" but is aware enough to throw a heavy object at the window of her hospital room.
