Is there really any value for the mentor at this point? That's the question you should be asking. But I already have the answer: There is none at best, and negative at worst. You are not a mentor if your goal is to down-bid a company for your proper gain; he is acting in bad faith. If you have no legal relation to this guy, simply send them a friendly email that you are no long communicating.
