In fact it probably has no influence at all. Given your “relationship” is nothing more than a 90 minute discussion and tangential to the actual admissions officers, you should not anticipate it having a meaningful impact.
I am sure the person you spoke to is well intentioned but unfortunately your circumstances won’t serve as a hook unless they are willing to lie about the nature, tenure and depth of your relationship.
That doesn’t mean not to go for it but build your list consistent with your credentials and discount this recommendation to avoid disappointment.
