One of the big theories that came out of Fantastic Beast: The Crimes of Grindlewald is that (SPOILERS) Queenie isn’t really joining Grindlewald: she’s actually a double agent a la Snape from the original series. Snape 2.0 if you will.
It’s one that makes sense in the grand scheme of things. She’s in love with someone who is in serious trouble of elimination from a dark wizard, so much so that she will do anything to protect them, like say spying on the bad guys for the good guys.
It would seem a little out of character of Queenie to kind of just up and leave her sister and her fiancée/secret lover after a single conversation with some guy that tried to kill her sister and destroy all of New York previously.
When you add in the fact that she has the ability to read minds (it’s more complex than that), she becomes someone who can uniquely infiltrate the ranks of an enemy combatant.
She’s in love with someone who is in serious trouble of elimination from a dark wizard, so much so that she will do anything to protect them, like say spying on the bad guys for the good guys.
The problem with that theory is that it does a disservice to the character of Queenie. Grindlewald is an excellent manipulator and is able to exploit vulnerable people to his side. She wants to marry Jacob, and Grindlewald feeds into this want so badly, that he makes himself be seen as the only way it can happen.
She tried everything, to the point of charming him, shanghaiing him to England, and then announcing to everyone (at least Newt) that they were going to be married. Her obsessiveness and almost crazy girlfriend vibes aren’t something random either.
As a Legilimens, Queenie is susceptible to sensory overload if she isn’t careful. Focusing on a singular person helps in this regard. If she isn’t focused or is distracted in anyway, she’ll hear everybody’s thoughts, a fact that is seen in the film.
This is why she can appear ditzy at times: she focuses on one person, and this can lend itself to her personality and her love of Jacob. It seems obsessive, but his thoughts are the only thing that she wants to listen too. Remember, when they first met, Jacob was one of the only men she’d ever had a pleasant conversation with.
And remember that Queenie isn’t just some random run-of-the-mill witch. She’s a powerful Legilimens. Queenie’s ability can be a major asset to Grindlewald; we see this already in the ending, where she instructs him on how to handle Credence.
She knows how people will think and what they will do, and if you give that power to someone with a silver tongue like Grindlewald and his title of the most powerful dark wizard of the time is earned.
Queenie being a double agent that mirrors the story of Severus Snape is nice to think about, but it also seems a little too much of a cop out. The Fantastic Beasts franchise needs to be able to prove that it isn’t just copying elements of the original series, and having a Snape 2.0 seems to cheap, especially to a fascinating character like Queenie.
