In Alpha Sapphire, you battle Wally before the end of Victory Road in the field of red flowers(reminded me of Remembrance Day a bit). Anyway, after being defeated, he said that he would stay there and train, meaning he would be able to rematch you. I finished the Delta episode and all that, and I return to Victory Road. I find that... HE'S NOT THERE. His parents in Verdanturf said that he went to the Battle Resort. I check there, and there's no sign of him. WHERE IS HE?
PS: I went to the Battle Resort before asking his parents and found the Magma Grunts and whatnot.
