There was an attempt robbery on Greedy that failed, done by two pokemon. Only his bag was cut and he is on the scene now has been watching the Machamp and what he and his trainer did. Maybe interacting with him?  

AS for pokemon Trainers can train 6 pokemon at any moment. But We as players cannot make a second pokemon character to be trained until we get our first badge or a part of the team that got the first badge.

Jaden adopted two pokemon that were previously stolen on route 1. Those two are more like npc.
