At first, Chimchar thought Paul was just standoffish. Quiet and awkard, not very good at showing his feelings or saying nice things. But it was okay, Paul had complimented his strength and let him join his team.
He hadn't realized the boy was just plain cruel until the japes and sneers started.
You're useless! I can't believe you lost us that battle, how could you be so stupid?
Calm down, we won the battle and that's enough. Stop making a fool of yourself with that stupid dance.
Ursaring, Torterra, attack Chimchar with everything you've got! This is the only way he'll get any stronger!
You should be grateful I let you stay with me after you've messed up so many times.
No matter how hard he tried, nothing was good enough for Paul. Paul, with his stony expression and his demands. Paul, who wanted nothing but the strongest and most powerful Pokemon on his team. Paul, the only trainer he'd ever known.
He never thought the moment the boy finally ditched him, someone else would be there to pick him up.
"Come on, Chimchar! You wanna go with us? I'll take good care of you and we'll get strong together!"
Ash smiled and extended his hand, his eyes filled with promise and sincerity.
"How 'bout it?"
Blinking back tears of joy, Chimchar let Ash pick him up and embrace him.
