Warning: SPOILERS for Doctor Strange in the Multiverse of Madness!
Doctor Strange in the Multiverse of Madness' post-credits tease important events and characters for the future, and it might all be set up for Loki season 2. The fifth Marvel Cinematic Universe movie in Phase 4 wrapped up its multiverse story with a big surprise at the end. Charlize Theron's Clea appears and recruits Doctor Strange (Benedict Cumberbatch) to help her with a new type of multiverse threat. All of this was only possible after Loki season 1's finale included the rebirth of the Marvel multiverse. And while the Disney+ show helped set up Doctor Strange 2 in this fashion, it is now possible the MCU sequel returned the favor.
Upon first glance, Doctor Strange 2's post-credits scene appears to be a tease of what will happen whenever Marvel Studios makes a third film starring the powerful sorcerer. The introduction of Clea (a longtime romantic interest in the comics), Doctor Strange growing more comfortable with his third eye, and agreeing to jump back into the Dark Dimension all seems like set up for Doctor Strange 3. While this could be the case to some degree, that doesn't mean that pieces of these storylines won't continue elsewhere first. The MCU already had Black Widow's post-credits scene set up Hawkeye, while Disney+ flipped the script as WandaVision's ending set up Doctor Strange in the Multiverse of Madness. These examples show how fluid the MCU's storytelling is between what will happen in the movies versus the shows, as well as how Marvel can use each property to prop up another.
