For the puppet master gym battle the trainer with the brozong never attacked or did any moves except for his musharna, im playing on the game z exe if that changes anything. it was like he was asleep and it just skipped the turn
If you faint/forfeit in the snowy cave (i forget the name) with Tristan he still has his occasional dialogue and you face him but hes no longer there to heal you or fight alongside you in battle
