A lovely followup to Are You Listening?, these form a wonderful short story that I'd ultimately about hope and life, and I love that this is a story with no real conflict, unique and beautiful.

Nice to see that the Doctor giving a sentient machine a chance works well - a touching, beautiful end, which, while sweet and poignant comes to a slightly disappointing end, especially after a strong introduction.

The Seventh Doctor returns with Bernice to correct his error several lifetimes ago and speak with Xenith. Unsure whether to trust and re-active it, the Doctor eventually gives in, and it's a beautiful night. You love to see it.
