The anime might have come up with another running gag and it is probably the best so far. Ash fails to catch Dunsparce when episodes focus on his relationship with his girl companion. I hope we'll see more of this. I just like how Ash wants to catch Dunsparce, it's the only time when he acts like a common trainer. I now wish for more filler episodes with stupid plots just to see this guy.
And yeah, that was the best part of the "date" episode and the series itself.
