Lulz, Rainbow Dash is such a drama queen. Just in a bit of a different way than Rarity.
Anyways, I forgot to comment on that last page so I guess I'll just be a little bit late here. Totally calling the aversion of the whole "Scootaloo is an orphan" thing in this chapter. RD (and the reader) is just jumping to conclusions, is all. We'll probably just find out Scootaloo's comment meant something totally innocent, or maybe her parents are just busy or something.
Anyhow. I'm excited now. I love drama queen Dash. Also, yay, more Twilight-Rainbow conversation on this page!
I kept Scootaloo's response vague because I didn't want to contradict any future possible canon. Besides, the story doesn't really revolve around Scootaloo being an orphan - that's just a motive for wanting to spend time with RD, which is the more important part.
Dash, this is a really dumb idea. Just bring her into your house for the week and help her afterweards; You'll teach her about responsibility much more that way, rather than pandering to her that may even cause guilt when Sweet Apple Acres loses bits because their crops dried up and died.
