Oh, but it doesn't have to be a deal. Going into a shop and seeing what is in offer is something minor. We could still poke this guy, see what does he have to offer, say what we can offer, without explicitly commiting to anything, and that is.
See, I get what you are saying. But you are also forcing the situation into discussing a retcon or making a deal, and that is not the case. It is not binary.
I'm not so interested in anything as to make more salt flow here, but tell me: does asking first, "browsing his wares", still count as being forced into a deal?
I think that we could simply handwave these incidents that are not so deeply thought as what they are. Yes, we had a desire to poke this guy and see what he was doing, and what we can get out of him. Even with no predetermined goal. If we don't find anything in specific, then we simply leave after pleasantries with no damage done to us whatsoever.
DP won't force us into anything. And while
@Goldfish might want to avoid social awkwardness by making a deal, the thing is that we don't need to do so to avoid being awkward. We had made deals with him before, and we had also rejected deals with him. There is already a commercial relationship with him, so to speak.
Does it actually hurt us to ask? We can always say no.
And the intention of this is just to calm things down. I think that we are going too far in the extremes and the decision is becoming binary, while it doesn't have to be like that. And it only produces more salt.
Now, most of this problem can actually be solved by format. DP wrote, in the update, that we would offer lore to the necromancer. Had he structured the question as "Do you make a deal with the necromancer?" then we wouldn't be having aproblem with this. We would be simply saying no, and that's it.
EDIT: Azel did tone it down already, I arrived late.
