Apparently Season 5 Episode 7 was Junior's first proper appearance. I dunno if that's crackpot or not, but it's a thing.

I'd love it if the aliens returned. We need more of them, and seeing a proper fulfillment of the prophecy would be badass.

The thing is though, I doubt the aliens will return if Halo 5's multiplayer doesn't have Sangheili as a playable race. They can do CG and stuff, but really, if they're gonna have one or more regularly-appearing alien characters, they're probably not gonna do CG just for them the whole time. (Which is why I'm praying for Halo 5 to have playable Sangheili.)
