So in the midst of his funk in Camp Dragonhead after the Great Escape, Alphinaud asks where we are going to go. Which leads me to wonder why he didn't even mention possibly going back to Sharlayan. I would accept that we, Tataru, and Yugiri might not have been allowed entry as foreigners, but couldn't he go back alone? Or is that not an option for him anymore; that he, and by extension, Alisaie, has essentially been barred from going home for leaving as Louisoix did?
