OK, I'm starting to feel a wee bit like I'm banging my head against a brick wall, and I don't know why. I have a completed and fully navmeshed interior, I have my NPCs, my dialogue etc all ready to go, I think I've got a grip on Scenes, but for the life of me I can't figure out how to replicate the event in Whiterun with the Alik'r warriors and the Guard that kick off the Saadia quest. I tried digging into it in the editor, but either I'm missing a big script package somewhere that actually drives the whole affair, or my brain is just rebelling in protest over the amount of tutorials I've crammed into it over the past week.
To clarify exactly what I want to do; the player enters Whiterun(at which point I'd have to force a check to make sure the aforementioned Scene with the Alik'r isn't active at the time), there are two NPCs talking, one of them storms off, the player gets a Misc objective to talk to the remaining NPC about the argument, that conversation leads to the actual quest.
Am I just going to have to essentially comprehensively learn Papyrus before I can do something that complex, or is it actually dazzlingly simple and I'm just being an idiot?
