William walked further through the town as the sun began reaching the middle of the sky. He crossed a bridge that led to a more nature filled part of the town that had a few benches standing around. He walked to the closest open bench and sat down on it before pulling out the book he had borrowed. He sat there reading for a little while until he heard somepony call for him. He lowered the book to see a mare with a filly on her back running up to him.
When she came up to him William could see that the filly was sick.

"Are you a doctor?" the mare asked in panic.

"Uh, yes. I'm a doctor, but no-" the mare cut him off before he could explain everything.

"Oh thank Celestia. My daughter threw up without warning just a few minutes ago and the hospital is on the other side of the town. Please help her." she explained.

William sighed. He could just tell her that he was more on the virus part of the doctor title, but he didn't want to let the mare down like that.

"Okay. Let me see her." he said.

The mare sat down and the filly slid down. William walked over to the filly and sat down in front of her.

"Hello there. Can you look at me please?" William asked. The filly looked at him, but seemed to focus on different directions at the same time, like he had more than one head.

"How many hooves am I holding up?" William said as he lifted up one hoof.

"Three?" the filly answered.

"Motion sickness. She's just very dizzy. Nothing to worry about." William said.

"Oh thank you so much Mr. .....?"

"Birkin, William Birkin."

"Well thank you Mr. Birkin. I am really thankful. How could I ever repay you?" the mare said.

"You don't need to. I'm just happy I could help." William answered.

The mare thanked him again and made her way back to the town. William sat back down on the bench and picked up the book again. Probably over an hour later he finished the book. He closed it and got off the bench as he began making his way back to the library. On his way back he noticed that the town was suddenly very quiet and empty. Like everypony just vanished into thin air. When he reached the library he opened the door to find that it was almost pitch black. The only light was a lamp that only lit up the table where a note was lying. He slowly approached the table and after putting the book down he picked up the note where only one word was written.

SURPRISE!!!

Right after he read that word everything happened to quickly for him to react much. The lights flipped on and most likely every single pony in Ponyville was there. Everyone shouted surprise and he got a face full of confetti. This all happened in under three seconds and he was just standing there with wide eyes trying to comprehend what just happened. When he his brain had fully processed what just happened he shook his head, wiped the confetti of his face and looked around. Everyone was partying and having a blast. Even though he was still confused he couldn't help but smile. It had been less than a day since he arrived and already someone had set up a party for him. It was so weird and made so little sense, that it was actually amusing.

"Hey William! William!" Twilight's voice came through the sounds of others talking with each other.

William looked in the direction Twilight's voice came from and spotted her sitting by a table with five other mares.

"What is this? Trying to get me a marefriend?" William asked when he came over to the table.

When William's words sunk in all mares at the table gave off an embarrassed blush.

"What!? No! Of course not. William these are my best friends. Applejack, Pinkie Pie, Rainbow Dash, Fluttershy and Rarity." Twilight said as she turned to face her friends. "Girls. This is William Birkin."

This was met with a round of greetings as William greeted back.

"So William. Are you a scientist?" Twilight asked curiously.

"Well, kinda. I'm a virologist. I study viruses." William said as a question popped into his head. "By the way. Do you know a place where I could set up my research?"

Twilight thought for a little while before coming with an answer.

"Well the best place would be Canterlot, but what kind of research are you thinking of?" Twilight said still not trusting him all that much.

"Well a little of everything I would say. Study a virus' behaviour and create vaccines for example." William answered.

"I can let that slide, but I'll request for you to be taken under a watchful eye. I still don't trust you that much." Twilight said "I'll send a letter to Celestia when the party is over." she added.

Just as the conversation ended, the lights dimmed and a disco ball was hung up on the ceiling.

"Alright everypony! Let's kick this party up a notch!" Pinkie's voice came trough some speakers as loud dubstep thundered throughout the room.

"Think you'll have to wait until tomorrow to write that letter Twilight!" William shouted through the loud music.

"Not the first time this has happened!" Twilight shouted back.

The two laughed a little at that statement before they joined in on the fun that would last until two o'clock.

Author's Note

Not the best chapter I admit, but I couldn't come up with anything better. The more juicy stuff (as in: G-Virus) will come later.
