This is AWESOME! This story just radiates such wonder and happiness, such charm. You really nailed Nine's voice amazingly, first, and Rose's amazement is also utterly adorable. I loved your descriptions of the TARDIS at the beginning, I love Rose's amazement that there was yet more beyond the door and the cute moment about the swimming pool—the "you think I don't read books?!" moment was also ten shades of adorable, and the whole "it doesn't need to have a point to be brilliant" discussion was wonderfully handled, a delightful lesson, good point well made. I love the mix between the simply and shamelessly cute (cheese! the casino!) and the most relevant bits of insight, like how the Doctor didn't "keep making" rooms in the TARDIS, it was the TARDIS that was a wonder in and of herself. The TARDIS' presence was very subtly conveyed all throughout, the whole background of this marvelous discovery—you could just feel that it wasn't just some big place or some spaceship, it was a box of wonders, a whole universe of its own. And full of stories. And random, beautiful blocks that don't have to be for anything in particular. ^_^ It's gorgeous, and very nicely leading up to the ending and tying up into canon. And I said it before, the dialogue is just a delight :D Just loved it! Thank you for this :)
