They really are a cute ship! I'd want to see that 'love poison' incident kind of make them realise that something really could spark between them!
Also, a fan-child of theirs (Merrilay, by ) is one of my absolute favourite-looking OCs. It's just a shame that she's an ax-crazy, pure evil sociopath in the related fic. The fact that Merrilay is a Pegasus also fits into my headcanon that Cheerilee and Scootaloo are still sisters in G4, but due to their parents separating before they knew Scootaloo was being expected (Cheerilee went with her father), they have no idea that they're related.
