The chain side-play has not been ruled out, still the most likely culprit in my opinion. I often found drive train problems surfaced after a chain cleaning or a drive train overhaul on a customer's bike.

As to the digression, my parsing of the two terms comes from my time in a crisis counseling center. Confrontation is firm setting of a limit and a request for change, whereas aggression is forcing of one's views (or body of course) on another. There's nothing wrong with confrontation done responsibly - it assumes the other person is strong enough to hear a frank appraisal and has both the ability to change, as the right not to do so (though that may have consequences). Aggression denies the rights of another person.
