I'm really surprised that they're bringing Harley back so soon. In a good way, of course. It looks as though they might be making him more important this season than he was in Hoenn. And I think there's a good possibility of Drew being in this episode - it's not like him to skip a nearby contest. Unless he'd already got a ribbon from it, but that would suggest that Saffron holds a contest once a week or something - it only takes May two(?) episodes to get from wherever the Arcanine ep takes place to Saffron, so presumably it would take Drew the same amount of time to make the same journey in reverse.
And Harley is confirmed to be gay by his personality.
