chunk: Grocer decides to kill Bart himself to impress Martin's client. Martin abandons the contract and rescues Bart from certain death, driving him to the Newberry house and holing up inside, narrowly ahead of Grocer and his team of mercenaries. During the siege, Martin finally reveals that he stood Debi up on prom night to enlist in the Army to protect her from his homicidal urges. Martin gradually kills the team of mercenaries. The NSA agents are gunned down by Grocer and Martin. By this point, Martin has run out of ammunition, and when Grocer tries to trick him into "selling" him a weapon for $100,000, Martin kills him by crushing his head with a television. Injured and winded, Martin proposes marriage to Debi, who, shell-shocked from the day's events, does not respond. In the end, Debi and Martin leave Grosse Pointe together.
