you are correct. ill put it in black just incase others havent seen it and dont want it spoiled
a war re-enacter guy and his friend were screwing around with a bazooka or something along those lines and it gets lodged in the guy but doesnt explode. when alex finds out what it is he runs to stop the surgeons from cutting into the guy and trying to remove it.
bomb squad comes in. meanwhile bailey is having contractions and needs to deliver her baby but wont because her husband isnt there yet. but she doesnt know that he got into a car accident rushing to get there and derek needs to perform brain surgery on him.
so the paramedic played my christini ricci had stuck her hand inside the bomb guy holding the bomb in place and she cant let go until the bomb people situate her in a good place. but she freaks out and merideth slips her hand in there to hold it. so they move the body ona gurney thing down the hall because the room they were in was over an oxygen line and if the bomb blew, everything would blow up.
so they move to the other room. derek begins surgery on bailey's husband, george convinves bailey to start pushing and have the baby.
they remove the bomb from the guy and the bomb squad guy starts to slowly walk out with it in his hands... after he walks out the door merideth follows out a bit and sees him walking down the hall to to bomb squad buddy and then BOOM! it blows. he's blown to bits and merideth gets blown back and falls without getting seriously hurt.
that's the majority of it. so that person was the only one to die i believe.
more stuff happened in the second but i dont remember everything

it's been awhile
