Bright as a match on the bottom of the Mariana Trench, indeed. But anyway, after going over Johnny's profile, I do feel like he and Aiden would be friends of some sort. Both share a rather chill attitude, in a bit different ways, but still, with Aiden's attitude being a bit more on the happy-go-lucky optimistic side. Aiden is also a person who loves fun more than anything else, except his family, of course, and as such, he's always someone to be looking for friends and trying to get acquainted with people, so it'd be likely for him and Johnny to have interacted a few times at least over the course of their years at Cochise.
The ultimate judgement is up to you, of course. I will be awaiting your verdict, Supreme Judge Frogue.
