This was a cute episode and it's funny that Opaline just sits around and does normal life stuff while Misty is gone. Sounds like she's too lazy to do the work herself and would rather have Misty do all the hard stuff.
I'd remove the inability to feel, numbness. As much as it can hurt to have too many emotions or intense emotions going on, being numb to things is scarier.
I think it's weird that the show made Scootaloo out to be an orphan for a while just to finally give her parents later. It was also weird when she said no one ever gave her praise even though that can't be true since her aunts were loving towards her.
