I've heard it's more sexual-tension-y if you play as a girl, although I never play as a girl so I have no idea if this is true or not.

Also Emolga is an adorable douchebag. I spent forever levelling up a Sandile so I could kick that gym's ass, because silly me, I thought 'oh, it's just an Electric-type gym'. Grrrrrr. Think I managed it with a Roggenrolla in the end.
