I dont think that they are going to kill him off. If you watched the first part of the 2 part episode...then you would know why silly. I really didnt get to see all that much myself due to me being in class till 10pm on Monday's.
I heard that he's officially dead at the scene but he's brought back at the hospital. They better not kill him off or they'll have ALOT of unhappy people to deal with.
