I just watched the latest
Atop the 4th Wall Episode, and the comic being reviewed had a weird dragon hybrid of sorts on the cover. The comments below revealed this to me...
Dragon + Unicorn = Kirin
So yeah, anyone trying to prove the Spike + Rarity relationship not happening just because you believe they wouldn't be able to have kids, consider yourselves beaten by Chinese Mythology. This is a mythical land of creatures after all, or did the multiple episodes that have mythical creatures not prove that already?
However, it was already beaten by the fact that you don't need to be able to have kids to have a long-lasting and loving relationship with your partner. At least this beats the thought all together and not seem like an idea the writers pulled out of nowhere in the first episode. It now seems like a legitimate possibility to me more than ever before.
Just something I thought you guys might like to know. That's all.
