The love between Vic and Melinda is a toxic spiral that somehow holds them together and at the same time very far apart. This tension is central to the film’s problem-solving. Melinda paraded her new mates in front of Vic and watched him sullenly fall deeper and deeper into a dark mental state before he was certain to be captured. When he’s caught, Melinda is scared at first because – well – her husband is a murderer. Then, how does Melinda rationalize staying with Vic the admitted murderer? Apparently, she wasn’t afraid of him because he killed her. So romantic?
Eventually, Melinda finds the purse of her missing lover, Tony (Finn Wittrock), hidden in a takeout box where Vic keeps an impressive collection of pet snails in the garden. After her initial escape attempt fails, Melinda makes the puzzling choice of burning the wallet and any evidence she finds. Here we have the best proof of where this relationship goes after the credits roll. Melinda made a decision.
Vic and Melinda have a relationship like no other. Even with their love affairs and sometimes murder, the two know the darkest corners of each other’s souls. They continue to live their lives as if everything was normal. It’s hard to say whether Melinda would find that kind of commitment elsewhere, given her own non-traditional leanings.
