Doing the quest to stop Potema, I went to Solitude temple of divines.

So there were these three priests hanging around.

Then suddenly Rorlund falls dead in front of the ex-shrine of Talos. The other priests run to him and after usual "oh gods" dialogue they run away from the temple.
What's up here? Wiki doesn't speak anything of this.

And I swear I didn't touch him.
