My own imagination about the result of this touching fanfic, about Rainbow Dash is actually Scootaloo's long lost sister…

Yep, I deliberately make their parents old, and their mom to be an earth pony, So that's why RD's parent's didn't really want RD to go to flight camp on Cloudsdale, and why Scoot didn't get proper lesson on flight (her dad is too old to that…)
Hope you like this…
