The cult recruiting was getting repetitive, but I felt like it had to be that bad to really drive the message home, that is, that Aqua's cult is just as stupid as Aqua herself. The ep was a bit less funny because of that, but I don't mind. It's just a single ep.
Umm... That rule is old and established. It's there simply so that if someone checks the thread without having yet watched the latest episode, they will notice not to read spoilers. It's common courtesy considering we don't have spoiler tags or other such annoying shit. So, yeah, I do "get triggered" because of it.
