"Hey, Rose?" The Doctor turned over in bed and whispered.

"Yeah?"

"Remember that ol' rock we saw in the museum with all that weird ancient language written on it, and when we were both coincidentally touching it at the same time, it translated into English?"

"Mhm." She smiled and snuggled up closer to him.

"And it was actually an ancient prophecy that said that we would be together forever."

"Yeah." Despite the fact that she had been there when it happened and had heard him recount this many times before, she liked to hear it again regardless. "And here we are."

He smiled and stroked her hair. "Can I just say, you're so amazing that even the ancient forces predicted your arrival and our fate."

Rose laughed. "You too."

He inhaled sharply and sat up in bed all of a sudden. "You don't regret marrying me, do you?"

"Of course I don't!" She frowned at him. "What a stupid question to ask. Of course I don't, and I swear I never will."

The Doctor nodded slowly. "Alright. Good. That's really good to hear."

"Why are you asking me this all of a sudden?"

"No, I don't know, it's just…" He scratched his head awkwardly.

"Are you feeling insecure again? Come here," she muttered and snuggled up close against him, engulfing him in a hug. "You know I will always love you. Don't be such a silly."

"Yeah, alright." He gave in and smiled tenderly at her as he reciprocated the hug, rubbing circles on her back. "I love you too."

She fell asleep in no time at all, and the Doctor turned his gaze to the window, out to the starry sky filled with planets and stars and great galaxies. He gave a melancholy little sigh and closed his eyes with what almost seemed like pain. Tonight, he wished that Time Lords had the ability to fall asleep as fast as humans did; he really needed it. Especially on this night when his mind…well, his 27 minds…refused to leave him alone. If you think overthinking feels awful, try overthinking but on a scale 27 times bigger.

He shifted over gently so as not to wake Rose, and turned off the nightlight, leaving him in the dark with his thoughts torturing him over and over again…
