Tranquil is very much sure he doesn't have a crush on his best friends little brother. He totally isn't into stallions cause that would be weird. Sure, he likes looking at Parfait's modeling pages (as well as some other male models) but he really does just buy them for the ads. Still, while he can worm his way out of blind dates his former crush, Sweet Deal, sets up, he can't yet figure out how to say no to the weirdly alluring Parfait.
Note: Tranquil really does have huge wings. Despite not being as athletic as his mother, he is an excellent flier. When stressed or frustrated (things he often is) he will challenge his mother to a race. While, at first, he would win since she never expected her nose-stuck-in-a-book son to fly that well, she eventually got used to his strange way of flying.
Also, I did something new with Parfait's mane. I don't know if I'll keep it yet but for now, it looks kinda cool.
