with a plan, and decides to pose as one of the victims. After being delivered by Loomis, Archer realizes that they are developing some sort of a bio-weapon. Archer begins destroying their technology, and kills one of the three Reptilians. Two others try to escape with the deadly bio-agent, and Archer kills another one as they flee. The last Xindi escapes due to the interference of Loomis, who T'Pol stuns with her phaser. On the factory's roof, Archer corners him as he attempts to release the bio-agent. Archer and T'Pol tag all non-21st-century artifacts, and return to Enterprise.
