She nods, embracing him, she then bites into his neck, drinking some of his blood, she then waited for his fangs to come out, when they did, she offers her neck to him
She smiles and then stops him "that's enough to fully turn you into a batpony like me" she nuzzles him, "how do you feel?"
"I feel... strange..." he said, not realizing his transformation was about to begin fully. Suddenly, his horn reverted into his head, his coat and mane darkened, leathery wings popped out of his sides, his pupils became slits, and his ears became more batlike. After the transformation was complete, he said, "I feel... so... alive... I feel... wonderful..."
Neon smiles "great, you will find you have a lot more energy, especially during the night, you will also be able to eat meat"
She nuzzles him "i love you Circuit, and i will always love you, and only you" she kisses him as they reach the table again
Night Skies smiles "now you're truly part of the family son" he chuckles and slides a small box containing a ring to him "when you're ready" he winks
Luna nods and nuzzles Night Skies Soarin' looks at Spitfire and coughs a little "Umm.. Spitfire, dear?"
He smiles "well we've been together for a good four years now and well i was wondering...." he kneels down on one knee and opens a small box "will you marry me?"
