>>34632335May made this face/blush when Brianna asked her if she liked Drew in that Battle Frontier Contest. May didn't realize she liked Drew till the tail-end of the Hoenn Grand Festival, that's why she doesn't blush over him during Hoenn. She was competitive with him because she didn't understand he was flirting with her.
Tomioka wrote most of May's Contest episodes at this point, and he wrote Drew/Harley's last episode, it's pretty obvious what he intended since he knew May's arc was ending at that point.
