Wasn't he actively trying to avoid meeting his disciples? Why is he directly heading to one of the ones with the greatest amount of influence in the world, one that can easily alert the others he's walking around?
@HDMI1 Iirc, he wanted to see the world and the accomplishments of his disciples himself rather than have his disciples show him around. He should definitely continue avoiding them if he wants to see how they're doing without them all rushing out to see him and show off to him but, he wouldn't be able to see everything without interacting with at least a few of his disciples. At least he isn't meeting with any of his disciples that became kings, or major politicians, or famous merchants, because they would be able to alert all 99 of the others almost immediately.
