"Well okay. Goodnight." Nathan didn't actually go to sleep. He went on his own little adventure. He returned to Union Cave and caught some more Pokemon. He went back to the Pokemon Center, seeing Hunter still sleeping. He put a pokeball on a table between the two beds. It had a sticky note on it saying,
"Dear Hunter,
I went out for a little adventure last night. Good news, I caught you a new Pokemon! This should help you with Bugsy!
It's a Houndour with the moves, Ember, Bite, Smog, and Leer.
Make sure to treat it well! It could disobey you if you don't!
Sincerely, Nathan."
After Nathan put this sticky note on, He challenged the gym, beat the gym, and started heading to Hex Forest.
