|~ Samantha in the episode "The Cat's Car"|
Samantha, more commonly known as The Cat, is a traveling con artist and self-proclaimed entrepeneur who claims to know the Conductor. She is able to travel across the train cars in her personal shuttlecraft, attempting to sell seemingly useless items to the unsuspecting inhabitants in each car. She has even owns and operates several cars on the train including the Lucky Cat Car, Le Chat Chalet Car, and her own namesake car.
Although her true name is Samantha, she appears to conduct business dealings on the train only using her title of "The Cat": the only characters shown to know her actual name were Grace and Simon.
Samantha is a short-haired, white cat with yellow eyes. In Book One, she wore a green, buttoned vest with a blue ascot. In Book Two, while running the Lucky Cat Car, Samantha wore a blue vest with a red ribbon and a skimmer hat. In Book Three, during her vacation, the Cat wears a light purple robe with a dark purple, fuzzy lining (which suspiciously matches with Frank's).
Samantha is a shrewd business-cat, always looking for opportunities to collect unique things and make sales, even of entirely useless items. Outside of her business schemes, her intentions are difficult to read: initially, she planned to deliver One-One to the Conductor and schemed with the Conductor to trap Tulip in her memory tape. However, as she later tells Tulip, she claims to always do the right thing, and indeed it is implied her plan to deliver One-One to the Engine was to help him regain control of the train from Amelia. She also genuinely cared about Tulip's safety, and even helped her get to the Engine to fight the Conductor; when she mistook Lake for Tulip, she was initially worried that Tulip was still on the train.
