Meredith, Izzie and Cristina see an ambulance coming around the bend and heading straight for them... while they're trying to unload people and get them into the hospital. Looks like an episode for the ages.
Freezing, choking, getting tongue-tied--there's a reason it happens. We lose our words because the stakes are so high and we have so much to lose. We're petrified of saying too much, or saying it wrong. When the truth is,the only wrong thing you can say is nothing at all.
