Cheng, Mahad and Lena are out installing a new sensor so they can tell when the Sphere gets near their block. Lena and Cheng are in the ship and Mahad is outside throwing his boomerang. Mahad gets ambushed by Sphere robots and they take him away. The Pirates find out that Mahad has been taken to a gladiator-type arena to perform in fights.
The arena is owned by the Sphere and Diwan drops by and is surprised to find Mahad locked up there (but considers him little more than Lena bait.) As Mahad nears his fight, Cortes, Dhalia, Lena, and crew all fly to the arena block and try to infiltrate it, but end up getting stuck in a cell.
Mahad starts his fight and is about to be beaten but Lena breaks through the wall into the arena. Then Diwan joins the fight and Lena and Diwan fight in mid-air while Mahad fights sphere robots with his would-be opponent's assistance.
Eventually, they have nothing left to do but jump...
