#d.i.d

Both of them represent the two different theories of cause

Bruce Banner's condition is likely the traumagenic model, as his father was an physically abusive alcoholic.

The different Hulks in Banners mind are:

Bruce Banner - the original persona

Savage Hulk - the child

Joe Fixit - the Las Vegas bouncer

Scar - the warlord

Devil Hulk - the caretaker

Note: the Devil Hulk persona died in Immortal Hulk, the same series he was introduced in.

Marc Spector's condition is likely the Sociogenic model, as he has been shown to have developed it seemingly spontaneously.

Marc's different personas are:

Marc Spector - the original persona

Steven Grant - the millionaire playboy

Jake Lockley - the taxi driver

Khonshu - what the fuck

Note: it has been stated that Khonshu made Marc's condition a lot worse, because magic fucky wucky bullshit. Marc always had the condition.

the main concept of "severance" as a concept is purposefully splitting the brain, (via brain surgery) to make two separate consciousness, one for work, one for home.

this is where it already gets tricky; its purposeful, it's basically consensual on the "host's" part, but the headmates (or "innies" as the show calls them) did not want this, but now that they have a chance at life, albeit a boring 9-5 box office job, they're content. (this is a point towards 'not plural')

some of them find happiness some of them find love, some of them find purpose, because that's what people need, proving that the "innies" are fundamentally people. (point towards 'plural')

i think a lot of the show focuses on the terror of waking up without memories, the utter horror aspect of it, and usually i'm quick to jump to "well this is the writers using d.i.d as a horror trope" because most of the time it is. (point towards 'not plural')

with severance; the horror aspects of the show are Real Terrifying Plural Experiences. as a system watching this show was lowkey eye-opening because i can show it to singlets and tell them "this is what its like." then they'll have a better understanding of my system and by extension other systems as well even if on just a surface level (point towards 'plural')

a lot of the struggles and conflicts in the show are centered around the "innies"(headmates) disagreeing with the "outies"(hosts) goals and ideas, etc etc there's LOTS of conflict between the two and absolutely NO communication between the two. (point towards 'plural')

the company who they all work for, has MANY strict restrictions on the "innies" ability to do almost anything, they are there to work and that is it. "innies" cannot communicate with "outies" and "outies" don't want to communicate with their "innies"(Schrodinger's point. could be either.)

SO. long answer; there are many many MANY Experiences shown, that are Real to Systems, yes the show frames it as a "wouldn't this be fucked up?" scenario, but it Is real and it IS (albeit. maybe slightly less? fucked up?) in real life and in real systems
