Have you noticed that the archive has messed up your formatting and duplicated your text? It's done that to me a few times as well.
Your dialogue for Lulu is good as usual, if a little harsher than I would see her being for an offhand comment at that point of the journey. She seems to me to mellow throughout the game. That's just an opinion though. I still like your Lulu's temper and the way she punctuates her speech with Fira.
I'll just say again that I really enjoy the way you flesh out Wakka and Lulu and their relationship in a believable and enjoyable way.
