"Hey Ava," Lily said, walking into the compartment. Ava tore her gaze from the window and smiled.

"Hey," she said.

"Excited for the new year?"

Ava shrugged, looking back out the window, "I guess."

"Hey what's the matter with you? You love to talk about Hogwarts! It's your home."

"I'm just not in a very good mood."

"What happened?"

Ava sighed, "It's nothing. I just didn't have a great break. And the next Full Moon is the second day we're back."

"Oh," Lily said. The Full Moon was a touchy subject for Ava, since she was a werewolf.

Oh, I'm sorry, I haven't introduced Ava yet.

Ava Petersen is a 15 year old, muggle born wizard. She has light brown hair that reaches just past her shoulders, and beautiful hazel eyes.
When she was 7 years old, she was bitten by a werewolf, and thus, turned into one herself. Ava never really talked about what had happened to her; she liked to keep the details to herself. She didin't even tell anyone that she was a werewolf except Lily Evans, her best friend.
Ava hadn't met any other werewolves. She didn't expect to either, considering they were so rare. As far as she knew, there were no other werewolves at Hogwarts.
Every full moon, she had to find a new hiding place for the night. If she got injured (Which was very probable), she would either pretend it didn't hurt so that her friends didn't worry or go to the infirmary and lie about how she got the injury.
It was a hard life for her.

"I'm sorry Ava," Lily said, trying to comfort her. "I'm sure it won't be that bad."

"I know," Ava said. "It's just bad timing. But it's not a very great start to the school year."

Lily was silent for a moment, "Well think of this: We're fifth years now! Think about all the amazing classes we get to take!" That seemed to cheer Ava up a little bit.

"I know," she said. "This is going to be so amazing! I can't wait!"

As the girls continued to talk excitedly, a boy passed by their compartment and watched for a couple minutes, hiding in the shadows. He knew the two gryffindor girls, and was pretty good friends with Lily. He had never had a long conversation with Ava though. He could never get the courage to talk to her; he wasn't like James, who was fine with making a fool of himself, as long as it got Lily's attention.

Speaking of James...

"Come on Remus!" James yelled, grabbing Remus wrist as he ran past with Sirius. Remus was yanked down the train toward their compartment. He looked back, and managed to get eye contact with Ava. She gave him a small smile, before James pulled him into the compartment.

"I can't wait to get to Hogwarts!" Sirius exclaimed, once they were all sitting.

Remus stared at him, "You're excited to go to school?"

Sirius rolled his eyes, "Not to go to school. To be at school; you know playing pranks, sneaking out in the middle of the night, annoying Snivellus."

"Hey, I was thinking that maybe we could... you know... not make everyone at school hate us?" Remus suggested.

"What would we do then?" James asked. "There's nothing to life without pranks?"

"Maybe we could work on our school work," Remus said, like he was explaining something to a five year old.

"But that's no fun!" James complained.

Remus simply shrugged.

"There is something wrong with Remus!" Sirius stated loudly.

"There is nothing wrong with me!" Remus replied.

"You're upset about something," Sirius said. "I can tell."

"It's nothing," Remus mumbled, and leaned back in his seat.

"Come on," Sirius whined. "You can trust us!"

"Why do you think smething's wrong with me? Why aren't you questioning Peter? He hasn't said anything this whole time!"

"Peter's always quiet,"James said. "Now tell us!"

"It's nothing!" Remus repeated.

"Remus you tell us or so help me..." Sirius said in a threatening tone.

"Fine!" Remus said exasperated. "It's really nothing though. It's just... the full moon is the second day we're back."

"That's not that bad," James said. "I mean, we're going to be there with you this time."

"It's too dangerous-"

"Nonsense! We're animagi now," Sirius reminded his friend. "You won't hurt us.

Remus was about to reply, when there was a knock on the door.

"Anything from the trolley, dears?" The nice elderly woman asked, like always. They ordered some candy and they spent the rest of the train ride eating, and laughing.

The full moon wasn't brought up again.
