***WandaVision spoilers ahead***


---------------------------------------------------------------


In episode 8 of WandaVision, we saw Wanda Maximoff arrive in Westview and visit the plot of land where she and Vision were going to build their new home before he died. Her grief then caused her to alter the town to resemble a sitcom setting, with the town's inhabitants all under her spell, essentially operating as puppets in the "cast" that became her perfect life.

What would happen if that plot of land was in Sunnydale, California (a composite version of the town from Buffy the Vampire Slayer seasons 1-7, so all of its inhabitants in that period were present)?

Could the Scoobies figure out what was happening to them and fix it? Would Wanda's power even affect the likes of Glory, Adam and the other powerful villains who'd be in this composite version of the town? What "roles" in the show would the most memorable characters from BtVS play in Wanda's altered version of the town? Would Anya/Emma Caulfield experience a form of Déjà vu?

Basically, what would happen if WandaVision happened in composite TV Sunnydale?
