10 MCU Loose Ends That Will Mean Something In Phase 4

3. "Too Many Sorcerors"

While the title of the Doctor Strange sequel suggests that we're going to see Nightmare as the big bad - since he inhabits the Dream Dimension right next door to the Realm Of Madness - there's an almighty hangover from the first Doctor Strange that Scott Derrickson can't just ignore. The small matter of Karl Mordo.

Having turned heel after the events of that movie, Mordo vowed to rid the world of sorcerors to ensure that the balance of the universe is upheld. He's got bloody murder on his mind and while he believes himself to be morally justified, he's clearly going to have to be the secondary antagonist of In The Multiverse Of Madness.

With Strange heading into the Multiverse to deal with something, you have to imagine Mordo will be furious at more meddling and it could even be that he aligns himself with Nightmare to try and remove Strange entirely?
