Now THIS is a good example of a great filler episode, right here.
I think the highlight of the episode comedy-wise was James saying, "Eurgh...well, you see, I like to look at myself in my spare time! Eh."
Absolutely priceless! XD.
In all seriousness, Ash shows how far he's come by his willingness to help Otoshi despite the chance he may miss out on entering the league.
