Be merciful

You walk up to her and stroke her hair "Tell you what cutie, I just need some money so you give me..." she checks the girl's account "100,000 and concede, I'll let you walk free." she looks up at you hopefully and nods. The pokedex chimes "Trainer Amy has lost by concession to trainer Red."

She transfers the funds before you even ask her and smiles at you. You are tempted to just keep her but you decide that since she kept up her end you will let her go, typing the commands in the pokedex registers her release and you tip your hat at her and be on your way.
