She's pretty effectively creepy so far
I'm curious about that as well, I wonder to what extent she's being forced to do this or if she's actually just evil. The scene where she hugs Conny's drawing on the wall makes me curious. Also I wouldn't be surprised if they pulled the "she's not human at all" card.
Also they kinda make the black lady out to be a good guy in OP with her hugging all the kids so I wonder if she's gonna be cool and help them out.
