Despite being less skilled in fighting than Vole, Jack defeated her by using a blowfish, causing a mark on Vole's hand. Nadia left and informed Sayle of her findings.Sayle and Nadia captured Alex and interrogated him. Eager to finish his plans, Sayle then left Alex to Nadia. After his departure, she dropped Alex into a water-tank which contained her giant Portuguese Man o' War. Trapped in this aquarium cage, he would either drown or get stung by the Man of War while Nadia was watching him, teasing him and tooking pictures as a souvenir of his demise.

This caused Vole to be stung to death.
