After a long time getting here, Ash and co. finally arrive at Mistralton City. Ash plans on challenging the gym leader but Mile, the previous Gym Leader, and grandfather of Skyla (the current Gym Leader), says that she's knows how the battle will turn out without having an actual battle which she develops an imaginary battle which she calls the "Air Battle" because every trainers around Unova flopped here to challenge her in an actual battle. So she became busier everytime and the time to persue her flight had been taken away. So Cilan challenges her to an actual battle to prove that her "Air Battles" are wrong in which he never tolerate any kind of battle she does. Can Cilan do it? No.
