He has returned.
I really want to see Ash face and defeat Cynthia, waited a decade for it. Having said that, Iris could actually pull an upset. I think Lance will defeat Diantha, should that happen, I don't see Leon facing him twice, meaning Ash would face Lance in the semis leaving Leon facing the winner between Iris and Cynthia. In which case, I could see Iris making it to the semis. Now of course Diantha could defeat lance and Cynthia defeats Iris meaning we could get a Ash vs Cynthia and Leon vs Diantha semi.
they would have to switch the brackets for the second round for that to happen, but unlike other tournaments these brackets and routes look pretty solidified.
that's pretty much what it boils down to with Iris advancing, because me personally. I'd rather see Cynthia take her out than the possibility of her and Ash fighting again, because all that happens is that she would lose again in a battle with higher stakes due to Ash's "plot armor power" and the impact could hurt her fans even worse than when Ash beat her last time.
