Kari's contributing to this not by saying anything herself, but by giving the tipped-off civilians a space to speak. She's holding a gala to "raise awareness for environmental concerns at home and around the world" and Riku gave her Maya's list of people who would be tipped off so she could invite them. She hasn't told them to talk about the water or even mentioned it, but she does know it'll be on their minds and in their speeches.

Basically, it's going to look to all the world like she coincidentally happened to have this generic event that concerned citizens who had already been tipped off happened to mention the issue at. Considering that the lead-up to Miss America is underway and Kari's affiliated with a rival pageant this year, it looks natural that she'd be throwing a publicity stunt like this.

Who'd be going and what's going to happen?
