#4. Why does Mike go back to Vietnam to find Nick? Be specific with this one and use examples.
Mike goes back to Vietnam to find Nick so Mike can settle the pain and loss of losing one of his best friends. In the middle of the movie, Mike returns back home (from Vietnam) without Nick. Mike, however, promised Nick's wife (Linda) that he'd bring Nick home for her, and his loved ones. Due to loss of communication during the war, Mike doesn't bring Nick home like he said he was going to. Mike can hardly face doing anything in his and Nick's hometown without feeling guilty. He can't even hunt deer properly without it affecting his aim. Mike could barley bring himself to face Linda and tell her that Nick didn't come back with him. Because Mike is so distraught by this awful guilt of not bringing Nick back, he goes back to Vietnam. While he's back there, he does whatever it takes to find Nick, including handing over $1,500 to the Russian roulette men. When Mike finally gets to enter the building where Nick is, he's crowded by all the betters of Russian roulette. The next game is about to begin when Nick appears in the room wearing a red headband. He seats himself at the roulette table, as Mike takes the opposite seat. Mike got lucky, however, Nick was not.
