The Doctor discovers both men have a large quantity of the metallic liquid in their blood, and explains that because the planet's atmosphere is impossible to recreate, should Voyager leave, they would have to leave the two behind. Soon, a pool of the liquid forms beneath the ship, and before they can lift off, the ship is partially sunk, trapping them. Torres discovers the liquid has the ability to take on the form of organic material.
The Doctor recognizes that both men have a significant quantity of metallic liquid in their blood, suggesting that due to the planet's atmosphere being unreplicable, if Voyager leaves, they must leave them behind. A pool of the liquid forms beneath the ship, and before they can lift off, the vessel partially sinks, trapping them. Torres observes that the liquid has the ability to take on organic form.
