She had to be. She was so much like him – quirky, smart, and completely brilliant. Luna was so much like the Doctor; it couldn't just be a coincidence. Multiple times, DNA had been taken from him. It could've gone anywhere, to anyone, produced any child, and perhaps this peculiar blond was one of them. It was definitely possible. River ran into her room and yanked open the desk drawers until she found the correct one. She yanked out papers covered in Gallifreyan and scattered them on the desk. Quickly scanning her eyes over them, she grabbed the one that read, "I am the Doctor, the oncoming storm" and a few others that had meaningless words on them, and stuffed the rest back in the drawer. She then gently laid out the selected pages on her desk and smoothed them out. The next time Luna had her class, she would ask the girl to look at these; if she could read them, if they were translated inside her head, River would know she was a Gallifreyan, a child of the Doctor. If she couldn't read them, it was just a major coincidence.

Meanwhile, Hermione sat at the Gryffindor table with Ron, Ginny, and Harry, Luna peering up to look at her from time to time. Each time she looked up, Hermione would be looking at her, but she dipped her head down and pretended to be focusing on the three friends she sat with. Eventually, Luna stood up and walked over to the Gryffindor girl.

"Hermione, may I speak to you for a moment?" she asked. "In private?"

"Of course," she answered, looking terrified but also intrigued and excited at the same time. The two walked out of the Great Hall, down the corridor, and ducked into an empty room, closing the door behind them. Hermione took a deep breath and turned around to face Luna.

"I think I'm in love with you," said Hermione breathlessly. Luna grinned.

"I feel the same way." She stepped towards her and embraced her in a gentle kiss. The other girl kissed back, and they stood in each other's embrace for a while before sitting down against the wall, just holding each other.

"So, I guess we're dating now?" Hermione said with a nervous chuckle.

"Only if you want to," Luna replied, and Hermione grinned at her, kissing her again. "I guess that's a yes," the blond laughed.

They sat, holding each other, for a while, until they thought it was time for class. With a tender, parting kiss, they went their separate ways, Luna to double Potions with Snape and Hermione to Defense Against the Dark Arts with Professor River Song. When Hermione walked in the classroom, River looked up and grinned.

"I'm assuming you talked to Luna, then," she chuckled. She must have seen the confusion on the girl's face, because she said, "Your hair's a bit muddled up, love."

Hermione embarrassedly smoothed down her hair as Harry and Ron, who seemed to be joined at the hip, walked in and took their seat. Soon, Pavarti walked in and took her seat next to Hermione, who was blushing slightly. They began chatting about something, probably girl stuff. River couldn't make out what they were saying from her desk. Soon, the whole class, Gryffindors and Slytherins, were seated and looking expectantly at Professor Song. She began the lesson with her usual greeting. Ron whispered something to Harry, so River whacked him on the back of the head with a rolled-up newspaper. The whole class giggled, and the ginger gave a sheepish smile. Harry laughed a little with the rest of the class. They didn't really cover anything major that day, and there was no homework assigned.

"Hermione? May I talk to you for a moment?" River called out as the class was leaving. The whole class was quickly gone and Hermione was sitting at a desk, facing River.

"So, how did it go with Luna, love?" she asked, genuinely interested.

Hermione grinned. "Well, it actually went quite well. There wasn't as much talking as I thought there would be. More kissing," she said with a nervous laugh.

The two discussed it a bit more and the younger girl left feeling happy. River was glad she could help the two. Why was it that everybody seemed to trust her and go to her for advice on love? Probably because she was quite brilliant at giving advice, match-making. After all, she had matched her own parents. It was a complicated story, but it happened. River chuckled thinking of this. How strange the universe could be. Suddenly, a previous idea rose up in her head – the idea of Luna. She was so much like the Doctor. She went back into her office and looked at the papers of Gallifreyan language on her desk. Luna would have class with her tomorrow. But now, it was time for lunch. As usual, the child of the TARDIS sat in her office alone, playing around with the ceiling. The TARDIS wasn't floating across the sky today. How she longed for it, the noise it made when that silly Doctor left the brakes on to park it. With every passing moment, River was more sure of the fact that Luna a daughter of the Doctor. Suddenly, she laughed. What were the chances, meeting her here? It was only on an off-chance that she had asked the Doctor to drop her off here to teach. The chances of meeting a daughter of the Doctor was almost zero to nothing, especially since she was a witch, too. Alas, she would have to wait for Luna's next class to see if she really was a daughter of the Time Lord.

With a wave of her wand, a teacup floated down to her and filled itself with tea and milk. A few sugar cubes and a spoon materialized and plopped themselves into the tea, the spoon gently stirring the liquid. River picked up the cup and took a sip. Perfect.
