Emily (Orange Islands)

Emily had a rivalry with her next door neighbor Ralph, as they caught the same Pokémon. When they caught the Nidoran, they split them (even if the Nidoran were in love). After their Nidoran were captured by Team Rocket, they set aside their differences and worked together after Misty gave them a telling-off, saying that what had happened was their own fault, and that they had only themselves to blame (which made Emily and Ralph realize that she was right).
