Following the events of Fight Club, the Narrator and Marla continue their romance, but their union is, as might be expected, far from happily ever after. While the Fight Club movie adaptation and the original book end in different places, both ambiguously suggest that Marla and the Narrator will remain together after the conclusion.
Chuck Palahniuk remains true to those implications for the sequel comic series, Fight Club 2 – written by Palahniuk, with art from Cameron Stewart and David Mack, lettering by Nate Piekos, and color by Dave Stewart. The series opens by revealing that the Narrator, now calling himself Sebastian, and Marla have been married for nine years, and they have an adolescent son together. Naturally, they couldn't be more miserable.
A Decade Later, Marla Hates The Narrator More Than Ever
In Fight Club 2, Sebastian has been taking pills to stop him from becoming Tyler Durden again. The medication has made him "boring" according to Marla, who is attending group meetings again. During one of these meetings, which Sebastian spies on, he overhears her groaning about how much she detests what both her husband and their relationship have become. It gets so bad that she replaces Sebastian's meds with aspirin, in order to bring back Tyler, just to fool around with him. Later, in Fight Club 3, she cheats on the both the Narrator – now going by Balthazar – and Durden, with random followers of Tyler's.
Marla Wishes She Never Met Tyler Durden
with her husband. That, in itself, eventually leads to her cheating on both personalities.
It's deeply ironic and deeply tragic at the same time. Marla craves a certain level of excitement, but too much of that excitement for Sebastian gives birth to mayhem. Hence, why Sebastian self-medicates, to prevent Project Mayhem personified, Tyler Durden, from being unleashed on the world again. He needs mundanity, but that mundanity has stilted Marla's spirit, perhaps stilted both of them. Dating back to the original Fight Club, Sebastian and Marla were two sides of a completely different coin, two clashing personalities, toxic for each other, but continually drawn to each other. The same is the case for Fight Club 2 and 3, only now that clash is pulling them apart.
