Serana and I were out in the wilds of Skyrim when we ran across a peddler and his horse fighitng some bandits. Unfortunately, we were too late to save the peddler. Well, Serana being Serana naturally reanimated the peddler to help in the fight against the remaining bandits. When the fight was over we pressed on with the reanimated peddler following along. What I found interesing is that the peddler's horse kept following him even though he was now a zombie. Talk about loyalty!
