Professor Juniper: "Oh, you've seen 300 Pokémon in the Unova Region!" "What a wonderful Pokedex! A little more work, and it'll be complete!"
"I'm really glad I asked you to do this!" "Keep up the good work!" That's it, nothing else.
When I show it to Cedric, he mentions the Pokémon Transfer Lab on route 15, and that's it. Nothing else there either.
