Katherine x Walter

Katherine x Walter is the het ship between Katherine Daniels and Walter One from the Alien fandom.

Canon
Katherine was the chief terraformist of the USCSS Covenant, a colony ship that was to transport 2,000 colonists to the planet of Origae-6. Walter was an android placed aboard the Covenant to monitor the ship's journey. When they first met, Kathrine was impressed with the amount of human likeness Walter possessed. She then led him on a tour of the ship. He Promised her that he would never let her down. Before the crew entered cryosleep, Walter gave her a checkup. He smiled during her speech to the crew during their final meal before entering cryosleep.

A year after the Covenant began its voyage, a stellar ignition hit the ship, resulting in the deaths of all of the colonists, as well as Captain Jacob Branson, who was Katherine's wife. A devastated Katherine then confided in Walter about how they had planned to build a cabin on Origae-6. While on Planet 4, Elizabeth Shaw, recorded a rogue transmission. While en route to Origae-6, the Covenant detected the transmission. Walter traced the transmission back to the planet, and the ship's destination was redirected to allow for an investigation. While there, Walter and Katherine discovered evidence that Shaw had been on the planet. They soon discovered that she was the sender of the transmission.

Soon after, Neomorphs began attacking the crew. When one of the Neomorphs lunged at Katherine, Walter shielded her, losing a hand in the process. A figure then appeared and fired a flare, scaring away the Neomorphs. He then led the survivors to his abode, where he explained that he was David, the android which had been placed on the Prometheus, and that Elizabeth had died. When David questioned Walter why he was so protective towards Katherine, he explained that he believed it to be his duty. Later, David encouraged Walter to practice the flute, and the latter returned to Katherine to play an original melody. While he was displeased with his initial efforts, she encouraged him to try again, and he played a melody that sent her to sleep.

After Walter discovered the truth behind the Neomorphs and Shaw's death, he fought with David. However, David escaped to the crew, and left the planet with the remaining survivors, posing as Walter. Just before he placed Katherine in cryosleep, she made a comment about her plans for a cabin. When David failed to recall the conversation, she realised his identity, right before he placed her in cryosleep for future experimentation.
