Yoichi, have you considered like... there could be consequences if you attack someone...

Anyway, Hien thinks Yoichi is just another person who's been riddled with unfortunate circumstances. He doesn't have much of an opinion of him, but is he like... an important npc? He has pokemon powers. Granted, one of them is just Splash, which sucks.

As for "whoever the Goomy trainer" was, he can't seem to make heads or tails of that person. Hope they got to live though. :')
