Not that anyone really cares, but this is the exact vibe I want my Welcome To Derry fifteen years later AU to have
I want my Welcome to Derry FYL AU to have a very domestic horror aspect, since IT is still a horror story, but given that it takes place between Pennywise cycles, the horror is reliant on Derry's social aspects and the people within it. The horror in this au comes not from Pennywise killing people, but what happens in between the times Pennywise ravishes the generations. What happens with the pieces Pennywise broke in the last one, and what horrors have to happen to set up for worse things down the line. As society pushes Ronnie, Marge, and Lilly to the roles of wife and mother, they each have to battle an inner conflicting that is horrifying all on its own- as well as outside forces.
Ronnie must figure out how she fits into her life as a wife to Will and a mother to Mike as she's spent so long in survival mode trying to prove herself to others she can't tell if having the career she's worked hard for or playing housewife to Will is what she really wants, while also dealing with being stalked by Clint Bowers on deaths door who holds the key to a secret that could put Ronnie's whole life in jeopardy. Ronnie's life is further complicated by the fact that her own husband is lying to her, using Ronnie's scattered memories as a way to hide the darker parts of Derry from her, something that, although Will means well, is not the selfless act he wants to think it is.
Marge must wrestle with feelings of still trying to please others, as she becomes embarrassed with herself and the life she's about to have, as she flip flops between feelings of inadequacy as a wife and mother for simultaneously having an imperfect kid, a husband she can't fully love as much as he deserves, and the fact she even wants to be a housewife at all in a time when other women are becoming more independent and free spirited than ever. But this all gets worse as she begins to suspect a spirit is following her, and if not, she's going insane from the sudden changes in her life. Is the only thing keeping Marge from moving on and being the best person she can be imaginary walls, or is the unfinished business manifesting in something more supernatural? Marge can't decide, in fact, she can't decide on much of anything.
Lilly has it possibly the worst of all, with her facing much of the same confusing feelings of what she wants being different than what she has. She must grapple with her own glaring flaws due to her unresolved trauma, which manifests in her rushing into various things without realizing the price of them. She marries a guy because she eases the guilt of her past trauma, she has a baby because her friends do, she doesn't listen to other people's concerns because she's been too burned by others in the past. Lilly will struggle as she tries to fight for dominance and control over her life, attempting in vain to force a happy ending for herself once she realizes she can't have one naturally. She will hurt her son, and her husband, and eventually herself along the way because she is too immature and vulnerable for the life she thinks she wants. Worst of all though, Henry's birth will mark the appearance of weird trauma dreams and psychotic episodes for both Lilly and Butch, which slowly devolve them into a shared madness through no fault of their own.
