Back Door

[waltzh]

In Sootopolis City, there's this house to the right of the Pokémon Center.

Inside, you see some old hag saying something about him being a trainer in his youth.

And then you would notice some ornamental plants blocking some back door or something.

Does anyone know what it is, or why it's there?

It looks very suspicious.

When you use a E-Reader Battle Card in the game those boxes will dissapear and you will battle the trainer that was in the E-Reader Battle Card.

What's an E-Reader Battle Card?

[Pokemon Trainer Sarah]

You have to buy an E-Reader and the battle cards from a store, but as far as I know, they're no longer being produced so they'd be hard to find.
