Polly was a young adult human woman with tan skin and midnight blue hair which is tied back in a bun. Given her appearance, she may be of Hispanic descent.
She was seen wearing a maid's uniform consisting of a black dress with a white frilly collar, a white apron around her waist, a white cap, and brown loafers.
Polly appears to have been the kind and obedient maid of the Sugarman household. Little else is known about her.
In a flashback from Time's Arrow, Polly is seen lacing young Beatrice's corset. Beatrice then asks her to bring a "pretty pill" and a glass of water, to which Polly obediently leaves the room to retrieve.
- Her surname is not known. It is also possible that "Polly" is a nickname, in which case, her full first name is also unknown.
- In Time's Arrow, she calls Beatrice "Senorita Sugarman" implying she's Hispanic.
