I have had my "doube kills" as well. And from someone from whom I didn't exactly expect it. Namely it was the Revianne, from the Harper Hold quest. I was in Umar Hills, on my way to the ranger cabin, when she and her party jumped on me just behind the village. I tried to be benevolent, but it came down to blows anyway. And so the fight was over shortly, they were really no match.
After some time, I went back to the city and guess who waltzed to me at the Copper Coronet? Revianne again. Well dang, what a pest, one time beating was not enough as it seems. So we talked again and again I tried to be reasonable and again she didn't want to understand how fruitless her "quest" is and, again, she and her lil' pals got spanked hard.
But hey, who am I to say no for some fun, free loot, free cash and extra XP, right?
