Unfortunately for that, though, is that the school opens today (June 1st), so I don't have much time to toss up a post without backdating a lot. I've mainly held back putting up a post about it since May was pretty full of events and I was on hiatus for a portion of the month.

Perhaps if Apollo is in the area of Goldenrod, he could drop by the opening of the school to look around and then be convinced by someone there? The school is pretty much looking for teachers/students 24/7, so he can always become a teacher then.
