 T 'Pol is able to communicate with Archer after gaining use of the universal translator. She learns they have been overcome with an overwhelming instinct to reach a city called "Urquat", the homeland of their species. Meanwhile Commander Tucker and an away team of MACOs, equipped with biohazard suits, manage to capture and return Reed to the ship. Archer and Sato flee and T'Pol opts to stay with them. Doctor Phlox soon determines that they were infected by a mutagenic virus, and concludes that T 'Pol's Vulcan genetics rendered her immune.
