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

Rating: Null/10 (20 December 2011)

Mike went back to find Nick because he made a promise earlier (after the wedding scene) in the film that he wouldn't leave Nick over there. Mike is a humble and honest man and couldn't settle back down in the U.S. knowing that Nick was still in Vietnam. When Mike got there he walked through the hectic streets of Saigon looking for the Frenchman that had lured Nick into the gambling of Russian Roulette. Mike arrived at the building that Nick was in and when Mike approached Nick, he could tell Nick had no recollection of who Mike was. Mike quickly noticed that Nick was traumatized and had physical damage to his arm that showed heroine addiction. In the end, Nick ended up losing Russian Roulette to Mike and shot himself. Mike was unable to fulfill his promise to Nick even though he tried as hard as he could to do so.
