Fans who knew to expect a second post-credits scene got to see an even bigger spoiler about a potential “Doctor Strange” sequel (should there be one).
After Strange defeats the villain from the dark dimension, Baron Mordo (Chiwetel Ejiofor) no longer sees eye to eye with Strange and goes to find Jonathan Pangborn (Benjamin Bratt), a paraplegic who learned how to heal himself.
In the scene, Mordo finds Pangborn in his workshop. Pangborn evidently feels that something is off and grabs a weapon. Mordo incapacitates him, sending him back to his former, paraplegic state.
Near the end of the scene, Mordo tells Pangborn that he has figured out what’s wrong with the world: “There are too many sorcerers.” That suggests Mordo could emerge as a primary villain in a sequel.
