A new promo just aired on ABC tonight, and while it was almost exactly the same as last Thursday's, there was something different about it...we saw the Ferryboat... Check this out from mfkngst at the ABC Message Boards:

Okay, I just saw the new promo. It's the same as the one that aired after the previous episode, except after Izzie says "Holy mother of..." we hear her finish, and say "God" then it pans out and you see the disaster, the ferryboat, on fire, and smashed up. Like there was an explosion on one end.
