It’s pretty bad! She says she only wanted to destroy the Grove because she was under mind control and that if she is kicked out, she will fall under it again (whereas nothing bad would happen to Halsin if he were kicked out). If she just had to leave but nothing bad would happen to her, it would be fine. As it is (which might not be the final version), it makes Halsin look cruel, which doesn’t fit with his character.
