Old lady

The old lady is the main character of the song "There Was an Old Lady Who Swallowed a Fly".

In Emily's dream, the old lady offered to use her magical powers to protect Emily from D.W., but she was lying and could not save her.

When Lydia and Brain (in wheelchairs) needed to cross a street without a ramp, the old lady assisted them.
