When Sol killed Mae and Osha's mother he did so because it appeared she was trying to absorb Mae's life force into hers, Mae could even be seen beginning to vanish. He thought she was killing Mae, yet he doesn't explain this to either of the sisters. He tells them he did it to protect them but without explaining what Mae's mother was doing, or at least what he thought she was doing, his claim of protecting them doesn't make as much sense.
