I went to Riverwood to quickly sell some stuff to the Riverwood Trader, when I get inside I hear the sound of a sword being unsheathed, I look around and all of a sudden I see a person with full Thieves Guild armour running from one side of the room to the other, he didn't attack, neither Lucan or Camilla were attacking him nothing, I know Thieves appear a lot in Riften and the guards attack them but I think this one in Riverwood Trader is a glitch, he kept pacing back and forth etc, anyone else find this weird? Is it something of a quest maybe?
