So is Rainbow Dash officially Scoots sister now?
Scootaloo asked: "take me under her wing" and "become like my big sister"
Rainbow Dash answered: "so you're looking for somepony to take you under their wing, huh? yeah, i might be up for something like that"
so essentially, she's now her mentor. and sort of a big sister, but you can have lingering doubts because that's not exactly what dash said
another episode would tell us more
but seriously, dash taking on that type of responsibility seems like a maturity step for her
drawing status: forgot to do something, did that. now i have to color that, and then do some shading and i'll be done. :D
