Saba and Jazz had landed a few moments before and headed to the office. They saw Malak dissappear underground and followed close behind. Saba locked her blade on and threw her lightsaber through the tunnel at Malak, piercing him in the leg and forcing him to drop the trophy. She force-called it to her hand along with her lightsaber, as Jazz blasted Malak andthe Soul-Edge. He ordered Saba to go back in her Stealth X while he kept Malak busy. She suprisingly obeyed, holding the trophy at a higher priority than killing Malak. Jazz could take care of himself. He continued firing, if only to keep Malak and the Soul Edge distracted and at bay for long enough, and when Saba contacted him saying she was at lightspeed and heading back to base, he transformed and got out of there, arrived at the shuttle he had flown himself, and took off, headed the speediest way to the ISS.
Once he and Saba were back, they placed the trophy into a high-security vault, protected with ray-sheilds and every other precaution. Malak would just have to try to find another key.
