As Xander's team arrive at the Philippines, a group of Russian soldiers disrupt Xiang's party, and Xander chases after Xiang, in which Xander regains Pandora's Box, but is destroyed by Serena, who joins Xander's team. The Pandora's Box that was destroyed was also a prototype, and soon after a satellite crashes into a Russian stadium, killing innocents. In the investigation, the team deduces that CIA director Anderson is in on the conspiracy, having helped Xiang storm the CIA headquarters and not flinch when the CIA was being attacked.
