Actually, lesbian aunts is the current theory I heard. Although them just being her parents' sisters is also possible.



I think the second one is more likely.



Also, either way, they're horrible caretakers, given how starved Scootaloo was for familial affection and support, and how she had to go outside of her family to Rainbow Dash to have a caring bond.



It doesn't change my point either.



I think it would be a fantastic episode to have Scootaloo's parent return, and suddenly be back in her life, much to Scootaloo's unexpected dismay, due to them not knowing her at all.



And I still think juxtaposing that with the Apple parents being brought forward to the present, and how the Apple parents also don't know their kids anymore would be a fantastic episode. Especially if it's a two parter, so that there's enough time to really dig into the issue with all the characters involved.
