Music can be a lot of things. For some, it's a memory. For some, it is loss. It circles around us, and has of recall things that were, things as they are, things as they will be.

As Eight hears the song her hands reach up and she holds them close to her chest. She can feel... something. Perhaps it was resonating with her situation now. Making her feel the loss and isolation. Her face is neutral, but the tears... the tears flow freely.

She needed this cry, the Doctor. Needed it more than she realized.
