I for one am always on board for the continued saga of Ash getting absolutely destroyed by Bea. See, this is the inherent problem with dedicating your whole life to training your Pokemon, and none of it to training yourself. You've been travelling the world for 20 years and have absolutely no capabilities beyond yelling at your electric rat!
At this point, Bea has beyond established dominance- yet to his credit, Ash refuses to simply submit. Now, then, it's time to humiliate him.
