sometimes i'm fine and then i remember sylvie is addie larue coded.
OKAY HEAR ME OUT.
she's grown up in apocalypses- places where no one can remember her. where she can't make a mark on the world or the timeline. sylvie has never had a lasting relationship or friendship with anyone since she has to keep jumping to a new timeline. if she is spotted and makes a mark on someone or a place, the tva will find her.
it's genuinely so sad, and so justified on why she hates the tva so much and 'selfishly' just wants to live. like addie, she is invisible to the world and had to spend years, centuries even, growing up in the destruction and death of countless people.
all they both want to do is experience the joys of life, and have true relationships. to make a mark on this world (in sylvie's case, causing chaos and burning the tva to the ground). even if that's just working at mcdonald's and listening to records, she savours those moments. the bartender who knows her usual, the record store manager who calls her by her name, the boy working at the mcdonald's who admires her.
she finally has a timeline to enjoy, and she's not being hunted by an organization that wants to kill her for what? her crimes? for being who she is? her nexus event was (in my opinion, i strongly believe this) becoming a girl. they would prune her for 'crimes against the sacred timeline' because the timeline decrees her to stay male for the rest of her life.
(this also explains the lack of genderfluid lokis in this universe because hwr really said- nah make the lokis all male-presenting)
when a version, a young 8-year-old sylvie, decides she is a girl and shapeshifts into one, the tva takes her and destroys her entire life just because another universe has people with unique thoughts and feelings. she grows up without any lasting relationships, in apocalypses, invisible and wanting to live.
just like addie.
this is spiralling into a sylvie rant and i didn't even mention addie that much but you get what i'm saying. they're also both bisexual and when they meet a certain dark-haired person who is a twin soul that's had a terrible deal as well, they lean on each other and form a bond.
tl;dr sylvie and addie are both invisible, can't make any lasting relationships, and just want to live when they were screwed over at a young age.
