tactical officer, as well as Astrometrics, but in the episode "The Ties That Bind" he is revealed to be one of the crew aboard the Demetrius, a ship commanded by Kara Thrace and tasked with finding the way to Earth. In "Faith", the crew attempts to imprison Thrace, but Samuel Anders, in an attempt to prevent this, shoots Gaeta in the leg. Thrace leaves in a Raptor, and Karl Agathon agrees to wait until the last possible moment for her to return. Gaeta pleads with Agathon to leave early, as delay in reaching medical care will likely result in the amputation of his leg. Agathon refuses, and in the next episode, Dr. Cottle removes Gaeta's leg below the knee. Gaeta refuses general anesthesia during the procedure, saying "I don't want to wake up with my leg gone", and after the leg's removal, he sings to take his mind off the resulting phantom limb symptoms. Growing hatred of the Cylons In "Revelations," it becomes public knowledge that Saul Tigh, Galen Tyrol (both Circle members) and Samuel Anders (responsible for Gaeta losing his leg) are all Cylons. In "Sometimes a Great Notion," he notes to his friend Anastasia Dualla that she seems to have her smile back, but shortly after he leaves the room, she puts a gun to her head and shoots herself. He rushes back and desperately tries to save her, to no avail. In "The Face of the Enemy" (set between episodes 11 (Sometimes a Great Notion) and 12 of Season 4), Tigh orders Gaeta to take a medical leave of absence. Lt. Hoshi (with whom Gaeta appears to be having a relationship) places a five-pack of Morpha (presumably a narcotic similar to Morphine) into his hands just prior to his boarding the raptor scheduled to shuttle him to the Zephyr in order to relax. When the Cylons attack mid-flight, the fleet is ordered to make an emergency jump. The raptor emerges in uncharted space, most likely due to an error by the computer. Since they have no coordinates, everyone aboard is stranded—there's no way to calculate a route back to the fleet. It is revealed that, back on New Caprica, Gaeta was involved in a relationship with an Eight, and he made lists of important resistance members in Cylon detention, whom she promised to try to save. With oxygen dwindling, Eight secretly begins killing the other crew members
