OK, OK, OK, another fic idea I'll never end up writing...
Peter has a younger sister. Sister is our protagonist/reader/oc.
She is in the upside down, living a suspiciously normal life, pretty much alone.
Peter as Venca isn't actually killing people, it only looks like that, what he's really doing is dragging their souls to the upside.
So these people, Barb, Billy, Etc are waking up in the upside down and being found by our protagonist and she essentially looking after them, making friends; "nursing them back to health"; introducing them to her way of life.
Think of the upside down like Limbo. They are not alive but they're not dead either.
Prog is so innocent and in her own world it hurts. Not really living but existing, Contentment and daily routine. Think cottage core but the aesthetic is all off.
When they ask why cant you/we just leave she's like 'I don't know, I just never found a way out, never thought of leaving either. Besides Peter is here some where'
She doesn't realise that Peter is Venca. But she isn't afraid of Venca like the others.
Now it isn't until our boo Eddie turns up that things get cray cray. Cause he's got more deets than the others and he's like 'what the actual fuck!?' He also probs super, super baffled by her, doesn't trust her. And questions why they all made this seem like it's normal, when it's not.
Eleven doesn't know oc exists, because she's totally off radar. I'm thinking something to do with pre upside down, and the reason behind her being there. Like a trauma response, she's able to hide, the only person she doesn't hide from is her brother and for that reason Venca just casually watches from afar which spooks the others.
They all think she's trapped like them. When she probably could actually just walk out. But unlike the others she feels safe in the upside down.
Even better twist she could let them all go back, but she's actually really lonely and that's why they are stuck. No one, even herself realises that. Imagine the tension as soon as they find out.
The tears when she realises what's she done, who venca is and what's actually going on. Like waking up and loosing your shit, emotional angst. Abandoned again. The guilt, omg the guilt. The loss of all these friends she thought she had made.
I feel like out of them all Eddie would pity her and be the first to trust her again out of all them. Because yes its fucked, but none of them really knew what was going on and she had been wrapped up in it the longest that she had normalised it in her head.
They 'get over it' when they realise she can help them get back. And once they are all out she's back to her lonesome again.
We could go really sad and she let's them all go, while she returns to the upside down to keep her brother there.
Or
A slightly happier version of rediscovering the world and naturally making friends not the ones practically being held hostage. Finally the cottage core aesthetic is back on tract . Self discovery, healing- yada yads
I don't know about love interest l, probs doesn't even need one.
