The Twins are two peculiar children dressed in rather odd costumes that could be mistaken for make-up if not looked at closely. They have two pictures in the book, and judging by the sepia of the photo, this photo originated from either Britain, or was taken sometime after or near the end of the Victorian age.
The Twins appear as two short children, wearing sacks on their heads that have holes for the eyes, thick triangular eyelines with some makeup on them, and small black lips as the design for the mask. For their outfit they wear white baggy shirts with white shorts and white stockings and shoes.
In the movie, their appearance remains the same, however without their masks, they have pale gray, scaly skin with gray serpentine eyes and fangs.
Not much is known about the Twins' personalities, besides the fact that they are shy and quiet due to the fact that they do not speak to anyone besides each other. The twins also are very affectionate and attached to each other, as they are always together, and they only talk to each other.
In the movie, they are often seen communicating via incoherent snarls.
Not too much is known about their peculiarity, but in the movie they were capable of turning a wight into stone with just a glare, similar to Medusa in Greek Mythology. It was believed in the book they had a telepathic bond.
- The two may be considered as close friends of Abraham, considering the fact that he kept a photo of them with him in America.
- The pair are the first and only characters so far to have two actual pictures of them in the series. Other photos only show people who resemble the character rather than of the same people.
