Thank you so much for reading and taking the time to comment! I can say that Kai has about 7 cg's in the next update.
Eco not acknowledging any positive things about vulterus is mostly due to kai's influence. Eco in the start was "well, let's not judge a book by it's cover", and now he's all aboard the "screw you vulterus" train, which is mostly because of Kai.
Jayce is the one that contextualizes the club scene to eco after the meeting with talis, and provides that explanation/justification/ context. But yeah, eco is impulsive :)
