Ash VS Leon will probaby be a multi-part battle, like Ash VS Paul and Ash VS KukuiWell there's probably only 16ish episodes left after this, right? And the possibility of another break.
If Leon/Ash and Cynthia/Ash gets 5 or 6 episodes and there's breaks between them and at least 1 episode for Leon/Diantha or Lance, and a couple of episodes for farewell, that only leaves them with, what, 5 episodes for Project Mew plus probably at least one filler?
