Who is Marla? What does she stand for?
Marla is a tragic character who is both a source of annoyance and affection? for Tyler (and the narrator). The narrator feels that she already ruined the support groups he attends and when she starts showing up and spending time with Tyler, it's just too much.
Ever since college, I make friends. They get married. I lose friends.
He's afraid to lose Tyler (himself) in a relationship with Marla.
All the meetings, the AA, the NA, the need for them, it stops, why?
the narrator goes to the support groups to fill a void, to be with people who have actually "hit bottom" the place he never seems to be able to reach. fight club somehow fills this void for him as well, but in a very different way. it's the feeling of being a hero for a minute during your seemingly unimportant life where you work 9-5 sitting in a cube at a thankless job. the role you have outside of fight club becomes irrelevent when you're at fight club.
a couple of things that have not been touched on yet - Tyler burnes the narrator with the lye and tells him to focus on the pain because this is the greatest moment of your life. everything before and after this moment will just be a story. and also tells the narrator
"without death, pain or sacrifice, we would have nothing."
how does this unbearable pain change the narrator's life? he now has a scar that he'll carry forever as a reminder of what Tyler said and it seems to me that Tyler believes that fight club is not enough anymore, it needs to be kicked up a notch.
Another important thing going on, Tyler works as a "renegade" waiter at prominent hotel events and pees, sneezes, etc in rich people's food. Is this just another way he's getting back at society in general or the rich specifically? Again, is fight club not enough? The fight club mantra seems to be expanding into other realms. Where is this going?
that's all i have for now...
ps - also sorry to hear you haven't been feeling well... hope you're feeling better!
