Wanted to show the dragon pony couples I have in my next gen. I mean I do have Spike and Flurry Heart, but I draw them a lot, so, be prepared soon for a deluge of FlurrySpike pictures.
Rainbow Dash and Garble
Their relationship is...complicated. Their love was full of constipated emotion, and flying competitions. They claimed to hate each other as competitors, but there was something starting to grow between them, at least enough for Spectrum and Fireball to be born. However, Garble left, his ego and pony prejudice getting in the way of his judgment.
Celestia and Ember
Their relationship originally started as a political alliance between the ponies and the dragons. Ember denied there being anything other than professional courtship, but darn it, Tia was so...goofy behind doors and let her boundaries down around Ember. Eventually, Ember found herself doing the same towards her. Even if that goofiness can sometimes be a little embarrassing, she found it more endearing over time. Just as long as Tia doesn't make her talk about it.
Luna and Fizzle.
Fizzle was taught by Spike how to make friends with ponies (through Fizzle's own accord). Funny enough, despite being the first of the 3 to live among ponies, Spike was the last to hook up with someone. Fizzle started out working as a royal assistant in Canterlot like how Spike did. He became an assistant for Luna, helping her with the lavender and giving her someone to talk to at night other than herself. Their relationship just grew from there. He's more of the dorky shy guy that will blush super easily if Luna just smiled at him. They're both dorks, honestly, and spend their time up at late nights helping ponies with sleep and playing video games together at late dawn and early dusk.
