I also want to point out this picture by @phinik
It shows Solomon directly destroying the Shrivelfig in front of her. Almost like he’s showing her. Now remember, Anne was excited about this. She even says to Sebastian when he presents it to her, “is that what I think it is?” Meaning that this gift obviously meant something to her.
The Shrivelfig supposedly has healing methods if I’m remembering correctly. So I wonder if it gave Anne some kind of relief during one of her attacks. Instead of letting her just have it he destroys it right in front of her. Not only that but he looks directly at her and says “nothing can” in reference to her curse being cured.
Solomon definitely had it out for Sebastian, but the way he treated Anne makes me wonder if he was the same way towards her. Look at her face in that picture, she looks so defeated. She looks as if the hope she has is being taken away from her, and let’s be honest, it is.
