OK, so I've been trying to get Hidden Abilities through the Friend Safari, but it isn't working. Serebii says:
> With each person, you get up to three Pokémon within each specific area, with the third Pokémon slot appearing should the person have defeated the Elite Four, with them getting Hidden Abilities if the player has been online at the same time as you.
I've been online at the same time and I can't get Hidden Abilities still. Hell, I can't even get the 3rd Pokemon. Help? ;-;
