Idiotic! Why on earth would she.. spoiler
The queen.. after keeping "Adam" alive in the beginning, against her better judgment, when she didn't even know him, and had plenty of reasons to kill him..
Then all of a sudden, when he's finally helping her, he clearly cares, he's trying to help not only a particular human, but Also ALL humans... THEN she tries to kill him?!?!
It's so *beep* stupid, I'm almost at a loss for words.. it's just plain weird, and not really believable..
