The Casual Marvel Fan’s Guide to Doctor Strange in the Multiverse of Madness

What's up with the third eye? Who was Charlize Theron? And what is Black Bolt's power, anyway?

This article contains spoilers for Doctor Strange in the Multiverse of Madness.

First, what happened to the last scene, where Doctor Strange grew a third eye? Does this mean that he... is bad now?

The short answer is that we don't know more than you already mentioned:

The third eye suggests that we may soon be seeing a more powerful, and possibly more evil incarnation of our familiar Stephen Strange.

The long answer is that there are some other characters and powers, both within and outside this movie, that highlight the presence of the third eye.

First, and perhaps most obvious, is the so-called Sinister Strange that our regular Doctor Strange meets in an alternate universe earlier in the movie,

a character who has attained absolute power and has become utterly corrupt,

And who at one point reveals a very strange extra eyeball on his forehead.

Stuhlberg was previously reprising his role from Doctor Strange

in which he played rival surgeon Nicodemus West - but whenever Michael Stuhlberg appears in any of the films, audiences should be really happy.
