I haven't played the DLC yet, so this is going mostly off of what others have saying, but I'm kinda upset that Kieran isn't a right asshole. like, punching people, using scummy teams, and just straight up abusing pokemon. motherfucker was leading up to being the most cruel/edgy rival in the series (personality wise. that hair kinda balances it.) and they kinda fumbled it. the fact that this didn't end with drayton getting clocked in the jaw by an unhinged off 14 year old annoys me.
..if it turns out, however, that I'm correct in any way with how he acts, I'm gonna be happy.
