She is the one who leads Alex and Conner to the Baket Room in Red's castle (and most likely the one to clean up after them when they finish rummaging through the baskets). When she sees them again, she looks at them suspiciously, but doesn't seem to remember exactly who they are.
Appearance and Personality
She is described as "short and plump" with pink cheeks.
"She was appalled by the chaos they had caused. "I don't know what on earth you're doing, but I think it's time for you two to leave," she said. The handmaiden escorted them back to the throne room. This time, she watched them like a hawk as they sat on their stools."
"[She] stopped in her tracks and stared at them peculiraly, not being able to recall exactly where she knew them from, but clearly remembering that it hadn't been a good experience."
