So, I just realized how confusing this au is, so I'm gonna make it less confusing if ya know what I mean. I'm just gonna put what the musical plots.

DEH- Instead of Connor really committing suicide, he attempted it but failed, so he ran away. In the end he comes back (for the milk tbh) and Larry and Cynthia enlist him into addiction/suicide rehab. Everything else is the same as the original.

BMC- SQUIPS don't exist! Instead, Jeremy's SQUIP (Eric) is a (perfect) human and Jeremy meets him through Rich and Eric and Jeremy become BFFs (that's how he controls Jeremy). Plots the same tho.

Heathers- Veronica stops JD from killing Heather, Kurt, and Ram. He still gets the school to sign the note but disarms the 'bomb'.

Hamilton- same thing but modern.

21 Chump Street- same thing but Jared is Justin's cousin.
