Some time ago I related an encounter with not one, not two, not four, but three Louis Letrush outside the stables of Whiterun. Two were standing, and one was in the road up to his waist. I have screenshots at home which I'll try to remember to upload. Using the console, I got rid of the two standing Letrushs (their IDs bore no resemblance to his base ID), and pulled the real one up. What was odd was that he was bow-legged, as if riding the horse I helped him obtain from the Blackbriars. What happened to the horse is anybody's guess. A day later he was stuck in the road again. I decided to ignore him.
Yesterday I was leaving Whiterun, pausing to speak with the caravan trader. Strangely, I couldn't start a dialog with him. Instead he was getting up. Now, I told you about a recent encounter with a http://www.gamesas.com/topic/1331490-talsgar-the-psycopath/page__p__20028224__fromsearch__1#entry20028224, and who should come at me this time? Louis Letrush! Seriously, what was he thinking, punching me? He sang a different tune when the guards filled him with arrows. I think the lesson here is never to help others with their quests. Either that, or the goblets and tankards in Skyrim are made of lead...
