Tom

"I must commend you for making it this far in our lovely Gym, not very many people get here easily."
"My name is Tom. I used to be the Gym Leader here before Haruto took over. "
"But that's enough of that. You're here for the Gym Badge, correct?"
"Well then, you'll have to prove yourself to me before I let you proceed."

On Final Pokémon: "Well, it seems things have finally started to get interesting. It's time to begin the final test."
First Encounter: "Oh, hey! Glad you could make it here!"
"Welcome to the Battle Resort! Trainers from all over come here to train!"
"You might even see some Elite 4 Members here every once in a while!"
"What are Haruto and I doing here?"
"Funny story that, we actually live in that Villa over by the lake. A Bidoof Dam was destroyed, and there's no other ways of us getting home until it's fixed."
After Battle Resort cleared: "Hey! Just who I wanted to see!"
"The Dam is finally fixed, so the path to our Villa is clear!"
"Haruto's getting pretty hungry, so I should probably take him to get something to eat."
"Feel free to take a look around our Villa while we're gone. It isn't much, but it's home to both of us."
Dialogue Exhausted: "Hmm.. what should we get to eat.."
