I think people perceived that recent episode a bit too deeply, either that or I have missed something because I didn't think Spike and Rarity got 'together' I thought Rarity just prevented Spike from telling her because she already knew, and that his feelings didn't/couldn't alter their friendship because they're so close. But maybe that's just me? I dunno.
No pairing in a kids show is cannon dood, no need to be a jerk about it.Point is spike conffesed and after they were saved rarity could have flat out rejected him, but she was accepting of his feelings. Does she love him, well as a friend yes, romantically, no. However the latest ep did at the very least make it where such a thing was plausible in the future. (like say the series finale, lol.)
But yeah, kids cartoons don't really do official ships, but thats what fanbases are for, lol.
Actually, it depends on the show itself. But yeah, in cartoons romance is usually shoehorned in. I really like Spike having a crush on Rarity though, I'm sure it reflects a lot of real kids having budding feelings for someone older than them. I think Rarity inhibits a more motherly bond with him, but hey, I like one sided crushes. Sorry for coming off as a jerk though, last sentence was a bit too much of sarcastic humor.
