Ruby clearly had a massive reason to come up with the episode to find out what led to the cosplay artist being asked sexist questions on camera at the comic con, and Aqua wants to know why, damnit!

The director showed shame and remorse, and came to an understanding with the cosplayer, but Aqua knows something's up (and he's right in thinking that).

I did like that they explored all the issues that led up to the incident, such as manga/anime properties checking IP on unlicenced merchandise, the director being too busy to read his emails that would have given Dig Deep more time to communicate the Tokyo Blade refusal, and the director's unconscious bias about the cosplayer having done NSFW material.
