I think your plan includes a little too much justification for our own actions. If they want us to explain, reason out, or flat-out justify how we could do something, addressing it point by point is more effective because these two are geared to feel hostile towards us if we are the ones that try to point out something, it seems manipulative, not reasonable, because they know we have crazy socials even without buffs.
If they ask a question, and, by their own determination, it seems we are just telling the truth as the ask for it, then it is better, because they regain their own agency again, they have some control of the discussion. They are scared or worried about what we will do or say.
It's give and take, we have so much personal power and leverage in different ways that they feel like it is fair if they get to control the discussion a little more. Or that's how I'm picturing their view on Viserys trying to get into their good graces. Actions matter more. Be understated. Play down our motives. If they are curious, carefully explain them, doling out information as necessary.
