Chuck entered behind them when they discussed who would go first, however the moment he saw the gym leader Nessa, he stepped forward and said "I'll go first."

"I see I have stumbled upon the bright and shining beacon of Hulbury, my name is Chuck North, but you can call me yours!" he said, in a similar fashion to one Gym Leader of Pewter City.
