Jet's best at being a quick, tough item boy. It's a talent of his, and one that got him well rewarded. A quick dash to the NR arena and escorting back some vampire hunter to Mewtwo (Ricther couldn't get into the arena by himself) and Kyogre had earned him the right to select his own judge for the fight. A quick consultation with fellow drifter Clive gave him the idea to use Jecht as ref for his battle with Nikki.
The results were as predictable as a sunrise. Jecht quickly tore into the freakish Nikki for his outfit, his makeup, his choice of career... and on and on. It didn't take long for Nikki to leave the arena crying (Where a well placed machine gun burst from Jet made sure he stayed out).
Who said that being item boy was a bad thing?
