Chronologically speaking, this chapter occurred before Chapter 5. Enjoy!

"Excuse me, Professor?"

The history Professor that the woman was addressing lifted his head from the book on his desk. His office hours were almost never frequented by students, so he was surprised to see one at his door. "Oh, hello! Please, come in. Can I help you with something, Miss...?"

"Song," she said sweetly, sitting at the chair across from his desk. "River Song. I have your History 366 class." River had quickly become something of interest to a large bit of the faculty at Luna University. She scored perfect marks on everything set in front of her, from math to science to English, and even more obscure subjects like philosophy and quantum physics. It was astounding. She had become somewhat of an archaeology prodigy as well, accurately placing artifacts by home planet, species of origin, and even so close as a century in age. It was no wonder that the University had offered to pay her entire tuition for however long she remained there.

"Ah, yes, I remember you," he said, placing a bookmark in his book. It was amazing that paper books even existed anymore, but there were always cycles of retro fashion, bringing back things that had been gone for ages. This particular volume was his favorite Agatha Christie mystery, but he put it aside. "What can I do for you, River?"

"I had a question about something that you went over in class yesterday," she said. "You mentioned that humans came into contact with aliens in the year 3020."

"Yes I did," he replied. "The Silurians they called themselves."

"Yes, but that's wrong."

The Professor raised his eyebrow at her. "Pardon me?"

"The Silurians evolved on Earth before humans did; they weren't aliens at all. Besides, Earth had been running into aliens for thousands of years before that. I know that humans tend to ignore what's right in front of them, but surely the records go back further than 3020."

The Professor furrowed his eyebrows. "Are you questioning my sources, young lady?"

"I don't have to," River replied. "I was there." The Doctor had been as far back as the conception of life on Earth. They both went back to Berlin in 1942. She had seen the Doctor a few times since beginning her studies at Luna University and he told her stories of aliens from further back on Earth than most people would think. If they knew aliens existed, that is.

"You were- Excuse me, young lady, but I don't have time for this foolishness. If you have a real question then ask it. Otherwise, please leave my office."

River almost bristled, but she kept her voice smooth. "Fine. I'll prove it. When my archaeology study trip comes along, I'll bring you back an artifact from so far in the past, you'll have to believe me."

"Please leave, Miss Song," the Professor said, raising his voice. River only plucked herself from the chair and walked off, intent and determined.

Unbeknownst to her teacher, she knew exactly where to find this artifact - a little place known as Pompeii.

To clear up a bit of possible confusion, the end of Chapter 5 mentions River taking the circuit boards from Pompeii to "him"; this doesn't actually mean the Doctor, it means the teacher mentioned in this chapter. She has perfect proof for him now. :P I hope that helps!
