I've been going through pages of this thread and the highlights for a few days, what a wild ride!
Initially I theorized that DocHoliday wasn't Pam at all, but someone that really didn't like her and hatched this elaborate troll to make her look insane. Some sort of middle-aged "Mean Girls" meets "Single White Female" for Karens dreamed up to fill the quiet hours in the day between work and sleep. Who doesn't enjoy a good daydream or strange vendetta against your neighbor every now and again?
But one day it all went horribly wrong: not-Pam BECAME Pam, forcing all of her real life friends, family and acquaintances to start calling her Pam. This would explain why when she's ranting IRL about Fassbender and the like they just go along with it, because they know not-Pam just flipped her shit one day after photoshopping herself into being a hair model from an early 90s photo. We've all got that relative or old school friend that's not quite right but you do what you do for your people, I get it. You'd hope they'd do the same for you but you'll never know until you venture down that dark road yourself.
I figure now that Pam is actually Pam, lost in a wild maladaptive daydreaming fantasy that tumbled out into the waking world. Perhaps it all started out as a bit of fun, but there came a point where tall tales of hair modeling and knowing people in the film industry didn't cut it anymore. The dreams grew grander, the tales more grandiose.
So over time a whole new cast of characters entered the picture, randoms combated online and celebrities gleaned from the covers of U.S. Weekly and Star Magazine in the checkout aisle. Really, who hasn't stood there wondering to themselves what they would do if the Queen of England really was a reptilian hellbent on controlling the entire planet? What if I really were a hair model in the early 90s and some financier tried to bang me? What if I could wage wars in my mind against my enemies inspiring real-world consequences and control other people with my thoughts? Why exist in reality at all, reality is harsh and boring, when I could be the star in my own personal Game of Thrones that never ceases until I do!
It must be a fun, albeit insane, way to live.
