As for dialogue, I can’t think of anything specific since the romantic subplot came only as I was coloring this. But if I had to come up with something on the spot, it’d probably be Lavender either snuggling up to Giraffititan due to his naturally warm body:
“Ah, you are so warm~ Warm me up, Titan.
Or him drunkingly confessing to his grumpy partner
“Have I mentioned recently how much I love you, Titan? You’re my favorite dragon hybrid.”
“There aren’t that many hybrids so it’s a short list.”
“And you top them all.”
