#4 Why does Mike go back to Vietnam to find Nicky?

Rating: 7/10 (30 December 2008)

I believe that this sequence goes back to when Nicky, at Steve's wedding, demanded that Mike bring him back home, no matter what happened. Mike made the vow in that scene, and eventually kept it by the end. But, the idea of "no matter what happens" goes back to the scene where Mike and Nicky face off in Russian Roulette and Mike decides that there needs to be more bullets. Nicky immediately thinks that Mike is insane but he manages to get Nicky and himself up out of the pit. So they get the three bullets and begin the roulette, but there is a reason. Mike is willing to do anything to get out of the P.O.W. pit and save his friends (i.e. wedding scene) because that was his mission. "One shot". He only had that one chance to get out of there.
