Scully performs a necropsy on the elephant, revealing it to be pregnant — which is impossible, since the animal had never been mated. The tiger reappears at a Boise construction site, and is shot dead by Meecham when it charges at Ambrose; the zoo is shut down the next day over the incident. Mulder tells Ambrose that the tiger was also pregnant, and explains his theory that extraterrestrial aliens are impregnating all the female endangered animals as part of "their own Noah's Ark." Mulder thinks that Sophie too is pregnant and that she is worried that her baby will be abducted. Sophie confirms Mulder's suspicions when she makes signs for "baby go flying light".
