Put it this way: you need a password to use a secure router. I don't have the password, I'm not the network administrator.

I have an odd, special love for double battles. I suppose part of this comes from the fact that in-game, it makes it VERY easy to spread experience among the party, and can lead to rapid level-ups for Pokemon in training (plus, if I paid attention to EV-training, it's an excellent way to spread EVs around, after all, all party Pokemon that fight a given enemy 'mon get the same EV yield, unless a specific 'Mon holds an item that increases the yield or has Pokerus).
