If it hadn't been for the Beige fur, I would've been really sure it was actually Jeddi the Bewear. I thought Jeddi was actually the stalker, and was purposefully messing with Yandil's head (Both in the obvious open way and in a more sinister way) as a cover up. I mean, that's the trope: Someone is acting weird and someone is messing with him because he's being weird. Except that in reality its the messing with him that's making him weird, making the second person have some kind of underlying plot. (Usually to push suspicion onto someone else)

As for trusting the towns people, season 1 and two didn't exactly have the best track record on that. I know the positive/negative Relationship system worked differently, but pretty much every time someone claimed someone else was a stalker, it was just a personal bias against that individual. I just assumed You'd stretched that a bit into the "Guy who no one in the town likes" thing. Clearly a lesson learned for next round.

As for season 2, clearly you just need to be hired by Nintendo and turn it into an actual videogame people could play in their own time and not have to worry that the people running it behind the scenes get ground into the dust.
