Ash and Oshawott in “There's a New Gym Leader in Town!”

[putting away his Unova dex] Wow, he's using Herdier. I know who I want.

Oshawott! [Ready to go!]

Oshawott?

Osha-Oshawott! [Yep, let me at 'em!]

Do you want to battle?

Osha! [Oh yes!]

Awesome, then I choose you! [Note: It is obvious that the writers did not even think about evolving Oshawott after the Unova League as well. Who cares, right? As long as Oshawott is cuter than Dewott and Samurott, kids will automatically prefer it over the evolved counterparts.]
