Well Krauxis, if I remember correctly Gardevoir is actually capable of naturally communicating with someone they have a deep bond with telepathically. I'm not entirely sure, but I thought I either read or saw that Gardevoir has that psychic ability. I think it was actually from the anime, Ash met a Gardevoir that could to that or something... may not have specifically said that it was normal for them to be able to do that, but Lucario could too!
