In response to question # 4

Rating: 7/10 (23 December 2008)

Mike goes back to Vietnam to find Nick because Mike made a promise to Nick that "No matter what happens" he would bring him back home. Mike makes this promise to Nick in his drunken state after Steve's wedding while realizing that he may never come back home alive. Nick forces Mike to promise him that he will not leave him behind no matter what happens. This promise sticks with Mike after he returns home without Nick after their stay in the POW camp and after Nick finds Mike in a Russian Roulette parlor. In the end it is Mike's feeling of guilt of being with Nick's girlfriend and coming home without him, that brings him back to Vietnam. Mike does keep his promise to Nick and bring him home, but not until Nick meets his end at a game of Russian Roulette.
