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.
Also this is the second episode in which a Gym Leader gives away a badge without battling trainers. The first being DP165: Flint Sparks the Fire!
This is the third episode in which one of Ash's friends challenges a Gym Leader and loses. The other two being DP067: Crossing the Battle Line! when Dawn challenges Maylene to a gym battle first. And BW051: Enter Elesa, Electrifying Gym Leader! when Bianca just made an appointment first before Ash would challenge Elesa to a gym battle just to prove to her father that she can continue her journey.
This is the first episode when a gym leader from another town challanges another gym leader for instance Cilan, the Striaton City Gym Leader V.S Skyla, the Mistralton City Gym Leader.
This is the third time Ash looked up Swoobat on the Pokedex. First was BW027: Emolga the Irresistible! when a whole Swoobat group is chasing Iris, Axew, and Emolga. Second was BW056: The Four Seasons of Sawsbuck! when one Swoobat is with a Pokemon Photographer name Robert.
