It is a curious title, and I've been trying to put it into context. The 3rd Gym is a fighting gym and the episode before this was called "Lucario & the aura sphere of rage", so it's probably going to be the third gym. I can't see her winning, because she has very little battle experience (even with ambipom), plus 2 of her pokémon are weak against fighting. I think she should stick to contests.
