   Summary

   Sunday feels he lost everything after the events of Penacony and is left revealuating every detail of his life. Past trauma he has not addressed with his sister continues to bubble up, and persisting through his pain is not producing the same results it used to. Robin suggests joining the Astral Express and Sunday disagrees, but the crew become his only option. Fortunately he is accepted as the sixth passenger. As time passes, Sunday learns to exist comfortably, addresses his childhood trauma, and learns what love is.

   Please please please trust me that things end up okay. I just don't want to portray mental illness incorrectly. It's real and will be sad but I'm aiming for it to be uplifting.
