Pidonus recognizing that Konoka's been hypnotized, and not able to do much about it other than possibly using her own powers to try and keep some lid on the situation, could definitely have some influence.

I'm not planning for Pidonus to be at the concert, but she might drag Konoka away from the ticket brawl, then they go watch it and Pidonus helps snap Konoka out of it? (Bad news: Pidonus is going to end up in self-worship trance. Good news: She at least isn't going to be trying to enspell others into worshipping her!)
