La?s and his crew passed Nilheim, and helpful as he is, he of course offer to escort poor Telrav back to his camp.
Though he was a bit suspicious because Telrav was armed and started to run towards the camp, so he didn't really seem to be in the need of help.
Anyway, when I approached the camp, I found that La?s and his friends weren't the first ones to discover the place was crowded with bandits - the bandits were already engaged in a fight with some legionnaires.
The Stormcloaks arrived later, when both legionnaires and bandits were dead. Their leader kneeled and paid her respect to her fallen enemies. That was good to see.
(I use Immersive Patrols, which most likely was the cause for all this.)
