As she went through the city, Kyran followed her from a distance - enough to not seem to be crowding her, but also enough to be visible enough close to her...people could figure out soon enough who was assigned to. Whoever that hooded woman was, they knew full well that she had a death knight guarding her. So she had to be important. Eventually, though, as she pondered returning to the castle, Kyran was still there - even if she'd tried to lose him, she'd have proven (soon enough) to have no luck.
