WMG / The Babysitter (2017)

The reason why Bee still cares about Cole despite her intentions with the cult with his blood is because she loves him more than a friend.

Yes, I know it's really impossible in real life, but think about it- there's more reasons why she only wants the vial of his blood than having him be a human sacrifice like Samuel was- she could have a hidden crush on Cole, and why she ended up killing Allison in the first place. Her last scene after Cole rammed the car to her has some hints of this before she lost consciousness.

• Uhh... no. I'm pretty sure the movie director didn't want to go there with Bee's character. She may have had a sisterly type affection for him, or she may have thought they were best buds, but that was about it.
  • Because Bee is a pillar of moral character.
  • Turns out that in the second film, when Cole told her he had loved her, he changed her view of him and that he was perfect for another person she knew. But just for the first film alone could very well be that she wanted him to go with her so that she didn't have to search for another "top tier" innocent for the ritual.

Bee's wish made true through the sacrifices was because she was either a target for the bullies as a kid, or mostly because she was raped or abused by family members.

I mean, what else would Bee do the sacrifices for? She just wouldn't be strong and confident out of nowhere now, does she? This might be also why she really does care for Cole, because she didn't want him to be like her before she did the sacrifices.

• Nothing in the film suggests Bee was ever a victim of violent crime (much less, rape).
  • There's the monologue about her being small and scared, though that doesn't necessarily mean Rape as Backstory.

Bee got introduced to the cult by her babysitter.

This ties into the WMG above. Some years ago, Bee was like Cole — a meek little kid who got picked on. She may have also been being abused by her parents. Her babysitter did the same thing she does now, putting Bee to bed before sacrificing people, using Bee's blood to complete the ritual. However, the babysitter did really like her and have genuine empathy for her situation. So when Bee found out, rather than kill her, the babysitter offered her a chance to join the cult herself, and she said yes. Now, Bee's repeating the tricks of the trade she learned from the person who got her involved.

• Turns out that she met the Devil after an accident that lead to Phobe being in critical condition, and made a deal with him to save Phobe's life.

Bee was Grace in Ready or Not

Much in the same vein as the previous WMGs, Bee used to be Grace, and after a night of being hunted, she turned to the dark side, and made a deal so she would never have to feel weak and helpless again. Looking younger was just icing on the cake.

Jeremy will reappear in the third film
