Beginning: Ruby goes to lab, gets pokemon, NOT PIKAFIRE, Pikachu okay. Show feelings for Gary, confused, angry but also attraction. Gary arrogant, Ash may be more of her friend? Gary picks squirtle, Ash gets Pikachu because he lets Ruby choose first? Charmander unavailable or a fourth trainer gets it.
Travels a bit, catches a pokemon or two. (vulpix? Marill? Pidgey? Bulbasaur?) Show bonding, training and battles with them. Ruby picks Bulbasaur. Gary challenges her to a battle with squirtle, bulbasaur has advantage and wins. Squirtle dies, Gary upset and furious, secretly scared that training harder than he thought. Ruby is guilt ridden at Gary's fate.
Middle: Ruby travels to first gym which is rock so wins easily, believes she is better than really is. Ash tries and fails, forced to train harder with Pikachu. Ruby hasn't seen Gary, feels guilty. Continues to next gym, which is water and wins, Ash does too. So does Gary. But Ruby loses at the next gym, killing one of her pokemon. Loses confidence, wants to give up being a trainer. Mother wants her to come home. Gary feels mixed emotions due to her loss, sympathises, but has no feelings for her.
Relationship begins when Gary becomes jealous of attention Ruby is giving Ash for helping her (friendship) Too immature to cope, both sides, relationship doesn't occur? Or Ruby makes first move but is rejected, which Gary regrets but refuses to change.
NO SEX SCENES. THEY ARE FIFTEEN.
End: At Indigo plateau, Gary withdraws, deciding instead to become a pokemon researcher, Ash and Ruby battle, Ash wins but loses next match and comes third overall. Who was the greatest pokemon master? No one knows, but they had had the greatest journey.
