Rainbow Dash is really enjoying being an honorary big sister to Scootaloo. They hang out, she praises Rainbow's sweet moves- it's really the perfect relationship. Until Rainbow has to do boring grown-up stuff and ask to meet Scootaloo's parents. No big deal. Just in case something happens, Rainbow knows who to go to.

Except... Scootaloo keeps dodging the question. And nopony in town has a clue where she lives either.

Rainbow is getting worried while Scootaloo is getting more and more desperate to avoid an answer. Because what if that answer isn't cool enough for Rainbow Dash?
