The name given to Carol Danvers by the alien Kree in Captain Marvel was revealed last week, as so many modern film details are, with the release of images from an upcoming toy line. The initial theory that "Vers" is merely a shortened form of the character's surname is not only proven true by the newly premiered second trailer, but also explained in a subtle -- and incredibly clever -- way.

The trailer establishes the threat of the shape-shifting alien Skrulls, and the war with the Kree that threatens to engulf Earth, but the primary threads that runs through the new footage is the quest by Brie Larson's Captain Marvel to piece together her past. Discovered, injured at a crash site, Carol was saved by the Kree, and effectively made one of the alien race, but left with no memory of her former life. Now haunted by glimpses of her time on Earth, she seeks answer to who -- or, if Ben Mendelsohn's Skrull leader Talos can be believed, what -- she is.

At about the 1:30 mark, Carol is shown examining mementos of her past (snapshots, concert tickets, etc.), most notably her manged Air Force dog tag. A little more than half of the I.D. remains, displaying "CAROL DAN"; that means the other part reads, yes, "VERS." The implication is that the Kree found that partial dog tag when they rescued Carol, and logically assumed her name was Vers. (It's apparently not an official U.S. Air Force identification tag, however, as those list last name first.)

It's a scenario that makes sense, and certainly addresses the dilemma of what to call someone who has know memory of who she is or where she came from: Rely on the (mangled) identification accompanying her, and be thankful that it was a partial name -- and not, say, Social Security number, blood type, or religious denomination -- that survived the wreckage. "AB Neg Protestant" doesn't exactly roll off the tongue.
