Not only did he actually manage to track her down, but Duren acknowledges that it took some time. Then again, you have to expect that, I guess. He's traveling with an entire group of soldiers weighed down in armor (presumably). Zuleika, on the other hand, is traveling with only two other people. Not to mention Duren would have to stop at the towns and find out if anyone had seen her. ... Why am I derailing about this? Chael, when everyone from Zuleika to Duren to the dance competition announcer knows your name, it kind of kills the whole "mysterious" vibe you're trying to work. Oh. I guess that explains it. Not really, but, yeah, sure, let's go with that, why not.
