The Mysterious Girl

Not much is known about this shadowy girl, as she has only been seen in the Little Nightmares DLC: Secrets of the Maw. As The Runaway Kid begins his adventure, he quickly finds himself following this girl, as she attempts to make her own escape. At one point, she is seen to drop knotted sheets out of a cell window and climb down (the same sheets Six climbed up in Little Nightmares). She was shown to be escaping with a flashlight, but The Runaway Kid later finds it abandoned near a puddle of black, suggesting that she was killed and eaten by Leeches. It's possible that she is actually a illusion created from The Lady, due to that she created the Shadow Dolls.
