So I'll start by saying Brie Larson's Carol Danvers is Captain Marvel and we should all call her that.
My question is though is the title diegetic? Can we expect anyone in the movies to call her that?
I don't think anyone was called by their rank in the movie and I can't tell from the uniforms but both Carol Danvers/Vers and Dr. Wendy Lawson/Mar-vell could've been a Captain in the Air Force/Starforce.
Did I miss something about Carol taking on her mentors name or something or is Captain Marvel just what we, the viewers, call the character in the real world? It didn't seem like she needed or wanted a secret identity, she could just go by Carol.
