there's not much we can do to help Sen where she is right now. (we've tried.) her character is our blind spot. in recovering from trauma she's largely on her own.
but we know that staying a witch would help her, and that going down that path would also move her down her path as survivor.
the least we can do is help her keep from self-sabotaging her way out of witchcraft. not when she's worked so hard to get where she is.
