You’ve got a new Pokémon that you’ve been training for a few days. You know it’ll evolve, but you don’t know what its final form will be. You grind away, knocking off paltry foes to harvest experience and you begin form a relationship with your Pokémon. You actually begin to like its underpowered form; despite its mid-evolution flaws, its certainly got its charms, and hey, you’ve had it for ages now. You eventually you come to love it.
