What were the Mechanic's elders like? She had said they were like his own, strange though that sounded. Did they listen to her? Had she passed on the warning, only to have her elders dismiss her words as Alain's elders had dismissed his?He suddenly felt certain that this Mechanic had no choice but to go onward to danger. Once again, he knew how she must feel. A strange sensation, worrisome. How to make it go away? How to release the hold she had placed upon him?She had saved his life. Alain almost smiled before he caught himself. That was it. Several times she had helped him. The Mechanic had used that to influence him. No wonder the elders warned against helping. How to cancel it out? Like cancelled like. Power could defeat power. She had saved him, she had helped him. He would help her, perhaps even save her life. That would cancel whatever the Mechanic had done to him. He would be free of her. The logic had no flaws.
