Siamese

Russian: Сиамцы (Siamese)

The common name for Rex and Max while in The Pack and with the Poxy Sissies. In Russian, conjoined twins are often called Siamese twins, after Chang and Eng Bunker, the well-known pair from Thailand (then Siam) joined at the torso that toured the world in the first half of the XIX century. Siamese had in common only one leg, and have been surgically separated (presumably shortly after birth), with the deformed leg going to Vulture (for whom it was the right one), while Shadow received a full prosthetic in place of the left one. They both limped as a result.

IRL: Kurt Vonnegut is one of Mariam's favorite authors, and the concept of twins pressing together to form a single entity ("We were not simply close, we were one", as Vulture says; we also see them finishing each other sentences when they have a common purpose - in the scene with the Plaster Knight) is a significant plot device in his book "Slapstick"; the protagonists (a boy and a girl) have also been born with physical deformities, and isolated by their parents in a private estate.
