Plot summary
Matthew Scott is infected by a plant-like alien organism and hallucinates a life on earth involving the rest of the Destiny crew. Reluctant to bring the infection back to the ship, Johansen and Rush try to find a cure for Scott's infection on the planet while Greer leads a team defending their position against the aggressive plants. Chloe's alien infection protects her from infection by the plants, and a transfusion ultimately cures Scott, but leaves them both under suspicion of alien influence.
