He was plenty less accessible already in Magnostadt. He spent quite a long time there studying. I can't imagine he would have stories to tell in Kou for quite that long a time. Unless Kouen notices he can keep Aladdin around forever by promising (and delivering) a new big boobed girl to amuse him every few days. Though on the other hand Kou is exactly where Aladdin & Alibaba should be going considering the witch of Al Thamen is right there.
