Um, my idea I had was to code a conversation similiar to what the PC, Jaheira, and Jahaboam (merchant) do for the locket if in a romance.
But, I want a new conversation between two different npcs with the said merchant, without the PC interacting at all. I have no idea how to even begin to code this, even after looking at Jahaboam.dlg, JaheiraJ.dlg, and Dshop02.dlg....
