Yeah figure it's a bug on my end, when I was testing ways to get past them without dying in combat, first attempt I was just blasting with spells and near the end they turned hostile even though I didn't do anything different and killed me, after that I killed them through use of the teleport spell on 2 mages, which might be what caused the issue, no xp when the archer dropped dead then speaking to the remaining one initiated dialogue as normal for the quest, I refused the escort and only had to fight the survivor.
