This page speaks for itself. The anatomy needs work on Matilda, and I regret having Hyacinth be in a bra and sweats for this scene, but the story is progressed and we have a nice sum-up and we know where we’re going from here.
Pay attention to Matilda’s eyes. The purple and black means that Hyacinth has gained control.

 

An important note about Hyacinth’s powers – they require some sort of ‘opening’ when she wants to wear or manipulate a person like a puppet. She can passively read minds, manipulate objects, bring down fire from the heavens, whatever. She cannot get inside someone without some kind of permission. She isn’t sure why, but it may be because of the girl she was once. She isn’t too fond of this restriction, naturally.
