Polly

Biography
Very little is known about Polly. Her initial conversations with Beatrix, Ronan and Harry seem to suggest that she has been traveling in The Building for some time, although it is not stated if she is responsible for any of the helpful graffiti scrawled on its interior walls. Her experiences have left her pessimistic, and she casually dismisses the possibility that the others will ever return home.

Unbeknown to her new companions, Polly is traveling with at least two other versions of herself from other Earths; and for reasons that are so far unclear, these different Pollys take it in turns to pretend to pass themselves off to the others as the same person.
