It was quiet in the big castle; naturally, of course. It was so very late at night, the only sounds coming from Flash and Twilight's heartbeats as they hugged. For once in a long while, Twilight felt completely at peace. No concern about breaking up with Flash or feeling the constant want to return to the human world to see him. No, he was right here instead.
He exhaled softly. "Sorry it took me so long."
"It's all right. Sorry it took me so long too." She giggled. "Your hugs are pretty above average for just becoming a pony though."
"Really?" Flash asked, pulling away with a silly grin.
Twilight grinned back. "Nnnno, but I can tell you're trying, and that's more than good enough."
"Hey, you try having human hands all your life and then getting a pair of hooves instead." He sat down to the best of his ability, holding up his front hooves for emphasis.
"Fair enough. At least you get a pair of wings in addition to them."
"Wings?" Flash was immediately intrigued, glancing at his back with curiosity. "I can fly? For real?"
"For real!" Twilight echoed, spreading her own and giving them a rough flap. "The pony Flash - or I guess he's just the other Flash now - is a pegasus as well, so it makes sense that you have that trait too when crossing over to this world."
He nodded sheepishly. "So, uh, how would I get them to work?"
She smiled, turning and starting to walk out of the room. "I can teach you a little bit tomorrow if you'd like?"
"That'd be great! I mean, I should get used to this whole pony thing if I'm going to keep up with you." He followed her to the best of his ability, eyes occasionally drawn to her hooves so he could imitate them.
"I wouldn't worry. I still don't think I'm that amazing at flying," she admitted, though being embarrassed to do so. "My friend Starlight taught me how to use my magic as assistance, so I almost never fly with wings alone."
"Yeah..." Flash drew his gaze up to her horn. "Do I have one of those too?"
She glanced over at him to see what he meant. "Oh, a horn? No, only unicorns have horns. Alicorns, like myself, do too, but we're an amalgamation of all three types of ponies combined, so I don't particularly count it, especially since being an alicorn in and of itself is mostly exclusive to being a princess."
She waited for a response, but he was silent. "...What?"
He smiled. "You're incredible, you know that? Having such a big role in Equestria..."
Twilight blushed, averting her gaze. "I-it was my destiny! That's what Princess Celestia told me."
Flash gave a cheery laugh. "And then you go and say that you're not worth me staying here? Come on, Twilight!" He bumped into her slightly as they trotted along. "Not that I would've cared if you were a princess or not. I'm the one who doesn't deserve you if anything!"
"That is so not true!" Twilight argued. Seeing his playful expression, however, she smiled and teased him back. "Though, if you disagree with my choice—"
"No no, I don't!" Flash interrupted. "No arguments here!"
The two had a few giggles over the conversation as Twilight opened her bedroom door and led Flash inside. He seemed curious about it, like he had with the few things he'd seen so far, but it came to a shy halt as they both approached the bed. Sure, they'd both cuddled and such before, but sleeping together was the one thing they hadn't done.
Flash watched as Twilight slowly climbed onto the bed. "...Is this okay?"
She nodded. "Is it okay with you? I know you're used to how I look as a human, so I imagine it's a bit weird for you now."
He waved a hoof dismissively, smiling. "You might look different, but I still see the same the same old Twilight, human or not."
He attempted to pull himself onto the bed with his forelegs, only to miscalculate and flop face-first into the bed, earning a giggle from Twilight. He squirmed a bit at first, then went over to her side, being careful not to crush his wings as he tried to get comfortable. Twilight watched him, recalling fond memories of the past; particularly, the day before she first met him, where she encountered the same problem. It was funny to think that her life wouldn't be nearly as enriched now if Sunset hadn't stolen her crown.
"So..." Flash's voice brought Twilight out of her thoughts. "What's a pegasus like me to do about getting a guitar?"
She chuckled, amused that such a thing would be on his mind. "I'm sure we can find something to do for you." She laid down next to him as they cuddled, albeit semi-awkwardly. "I would definitely miss hearing you play otherwise."
He was flustered from the close contact, Twilight radiating an almost-magical warmth at such a range. It was nice; more than nice even.
"I could still sing to you?" he offered, though eyes slightly droopy. "Starting tomorrow though, when I'm not so tired."
She cuddled closer, nodding her head in approval. "I'd like that."
Flash smiled, nuzzling Twilight lovingly as they slowly fell asleep in each other's embrace.
