WandaVision showrunner Jac Schaeffer has addressed the way Elizabeth Olsens character was handled in Doctor Strange in the Multiverse of Madness. While many fans were unhappy with the changes made to Scarlet Witch during her final (yeah, right) appearance in the Marvel Cinematic Universe, Schaeffer has explained that it is hard to really get too attached to what other people do with characters in the MCU, as they are really just borrowed for the time a writer works with them.
