Clefairy is super tired having walked with Ash all this time lost. Not eating anything since Cerulean. Ash takes her to the pokemon center "Clefairy is super tired can you let her sleep here" Then Joey runs in with his Rattata. "He's been here 15 times this week. He keeps fighting surge, without training. Or using any pokemon other than Rattata"
Ash after a meal goes to Surge'a gym. Apon seeing Clefairy Surge points to her "Everyone look. The baby brought a girly pokemon." everyone laughs. "I'll show you! 1 on 1! I pick Clefairy!" Surge sends Raichu "I choose Raichu" Ash uses his dex to scan it and gets nervous after hearing it's entry "Raichu! Mega kick!" Clefairy was kicked to a wall and is nearly down. "Clefairy! You okay?" Clefairy just barely stands up "Again" Clafairy gets mega kicked again and faints. "Clefairy is unable to battle. Lt. Surge wins!"
Ash picks her up and rushes her to a pokemon center. Clefairy tells Ash she wants to battle and Ash decides to help her win. So Ash in game terms level grinded. He got back in the gym. "Just as we planned" Surge smiles "You planned?" Surge spammed body slam and Clefairy smamed double team. Raichu misses a thunderbolt and Clefairy slaps Raichu down. "I CAN'T BELEIVE IT!" Ash hugs Clefairy and recieves the thunder badge.
Ash having received his thunder badge in a difficult battle goes off to continue his journey. Hoping to see more challenges.
