So you know how in the second season the big monster possessed Will? What if instead of that, BJ's mom decides to ramp up the whole 'curse' thing to the nines, and BJ is suddenly forced to be clean, polite, and well behaved? And Lyds has to go back to Hawkins with Iggy and Ash to open the portal thing, go to the Netherworld, and confront her to fix it?
