Luciola also just goes "Well, bye then" and teleports out if you fail to bring Schera to the fight. LOL at least Falcom mostly learned going forward and generally required relevant party members to future such climactic fights. Though there are still some party choices in later games that end up being highly recommended because their dialogue is just way more interesting.

Edit: Oh, right. Next boss fight is the point of no return so bring your preferred endgame team if that matters to you. Like mentioned above I do think certain party choices yield more interesting dialogue but nothing remotely like the other Enforcer fights. Personally my recommended "dialogue" team would likely be Agate and Kevin but everyone gets something this time.
