In the route 32 in Johto, you were walking along the long path when a picnic girl decided to challenge you to a Pokemon battle. You won, but you expected it, after all she only had one Pokémon, but she didn't seem too disappointed, and looked up to you.

Liz: You really are a strong trainer! Can I register my number on your Pokégear? Then maybe we could challenge each other again and maybe I could let you know about some cute Pokemon I catch!
