Nike1000: I hate Petunia and since its AU I just thought I'd let her out.

Roxy Angel: Thanks a lot for the encouragement. I really appreciate it because it is my Harry Potter fan fiction.

Part 2: Diagonally
(A/N: This part starts out 11 months later from where I left off. So Lily will be coming to Hogwarts this year.)
"So Sirius, How does it feel to be in Gryfindor?" asked Mrs. Evans
"It was great, and my friends sorted in it too" he replied.
"Oh that's great honey, your father was in Gryfindor" she said remembering her first husband.
"What about you dad?" asked Lily trying to get into the conversation.
"I was in Hufflepuff" said Mr. Evans, who was Lily's real father and Sirius step father.
"I hope I get into anything, but Slytherin" said Lily, dreading the thought of it.
"Or Gryfindor" Sirius whispered to Lily.
"What's wrong with Slytherin?" asked their mother.
"That dirty Snape is in it" replied Sirius naturally before Lily could say anything.
At that moment they all heard the phone ring.
"I'll get it, It might be Jane" called Lily while rushing to the phone.
"Hello" said Lily
"HELLO" said yelled the person on the phone.
"Who's this?" said Lily a little scared.
"It's James, Is Sirius there?" said James just as loud as before.
"Ya just lower down your voice, the whole world can practically hear you"
"Oh sorry, I'm new to these things. My dad just bought a new muggle invention and I just wanted to try it out." said James a little quieter"
"So. Can I talk to Sirius?" asked James politely.
"Ya sure" "Sirius its for you, It's some guy named Jimmy" said Lily
"Jimmy?, who's he?" said Sirius confused.
"Oh, it might have been James" said Lily correcting herself.
"Ok" he said running to the phone without anymore conversation.
"Hey Prongs, Since when do you have a telephone?" asked Sirius.
"Oh is that what it's called? My dad just got it!" said James "So have you gone shopping for supplies yet?"
"No, not yet. My mom said that I have to go with my sister, so I'm trying to put it off' replied Sirius sounding like he really didn't like the idea of spending a day with his little sister.
"Oh I'm just asking because Me, Wormtail, and Prongs are going to Diagonally tomorrow
afternoon, and we wanted you to come. So can you make it?" asked James.
"Yeah, but I have to bring my sister along" said Sirius grumpily.
"Okay, If you have to" said James, a little bummed out.
"Okay, I have to o eat dinner, I'll see you tomorrow afternoon" said Sirius in a hurry, but still excited to see his friends tomorrow.
"Bye Padfoot" said James.
"Bye"
He ran to the dinner table, where his family was already seated.
"Mom, tomorrow can I go to Diagonally to get my supplies?" asked Sirius hoping that she wouldn't mention Lily.
"Yeah, but Lily has to come with you" said Mrs. Evans.
"DOES SHE HAVE TO COME?" shouted Sirius.
Both parents said "Yes"
"And don't speak about you sister that way" continued Mrs. Evans.
"It's not like I'm excited to tag along anyways" replied Lily sounding kind of hurt after her brother's words.
--------
Next Morning: Lily got up extra early morning to get ready for the day she was to have. She couldn't believe that she was actually going to enter Diagonally. She had heard so much about it and now,(even though she was going to be with her brother and his friends) she couldn't help but be excited. She got out of her gaze when she heard Sirius calling:
"Are you done yet?" Sirius said angrily.
"Give me one minute" she said annoyed.
"I already did" Sirius said.
"Alright, alright I'm coming" Lily shouted back.
Lily came down stairs with a pair or tight jeans and a skimpy tank top (At least in her brothers' opinion).
"What are you wearing?" asked Sirius, looking at her outfit.
"CLOTHES, like all the other girls wear" replied Lily.
"Well your not other girls. So go change...NOW!" said Sirius sternly.
Lily couldn't believe that he was acting like this. "Well, Mom told me I could wear it so to bad" (A/N: Don't think she's a slut because the outfit wasn't that bad).
"Well at least wear a jacket."
"Okay, but only to get you off my back" said Lily angry that her brother was treating her like a little kid.
So together they left to go to Diagonally, both avoiding talking to each other.
When they arrived at Diagonally, they saw James surrounded by a group of girls.
"Padfoot, Help me!". said James terrified. (A/N: Remember their only 12 and guys usually aren't into girls at that age).
"Don't tell me your scared of a bunch of girls" Sirius commented while trying not to laugh at the site in front of him.
After a while the girls left to go shopping.
"So have the other guys arrived yet?" asked Sirius.
"No, but they should be here any minute" said James.
They all sat down at the nearest table, to wait for Remus and Peter to arrive, but Sirius (like usual) had to go to the bathroom. So Lily and James were alone together. (A/N: Finally)
"So Lily, your coming to Hogwarts this year?" James asked, tying to make a conversation.
"Yeah, I got my letter of acceptance last month" said Lily, proud of herself.
"Do you like Quidditch?" said James, bringing up a topic that he always enjoys.
"Yeah, I think I am going to try out next year" she said excitedly.
"Oh cool, I'm trying out this year to be on the team, I hope I make it. What position do you play?" said James
"Well I like to be seeker the most, but I am better at placing chaser. What about you?" she said.
"I'm a seeker." answered James.
So, What team do you want to be on, Lily?"
"It doesn't really matter for me, but I prefer Gryfindor" said Lily. She couldn't James was one of her brothers' friends. He was actually nice to her. "But don't tell my brother because I don't think he wants me in Gryfindor" she continued.
"You secret's safe with me, But I hope you in Gryfindor because if your in any other team I'll have to kick your ass in Quidditch because I wouldn't go easy on nobody, not even my best friend's little sister" James said sarcastically.
All of a sudden they looked and they saw Remus and Sirius walking towards them with Peter lagging behind.
"So, lets begin shopping" said Lily in a rush to get started.
After three hours Lily and the boys had done all their shopping. Lily had gotten her, which took quite a while, since she kept blowing everything up. Peter left them half way to go get something, and he didn't return for the rest of the day. He didn't seem to like Lily much. When she finally picked out a wand and her other supplies she went to go buy an owl. She picked out a snowy white one, with a tint of pink. She decided to name it Marshmallow , which James thought of because the owl reminded him of one.
"Bye Prongs, Moony" said Sirius, sounding tired after a long day.
"Bye Padfoot" They both said in reply.
"What's up with the weird nicknames" asked Lily curiously.
They all looked at each other and Sirius replied, "Oh.. Nothing"
"Bye Lily" "Hope to see you next year... in Gryfindor" James whispered I her ear so only she could hear.
She winked at him and said bye to him and Remus, as they all parted outside Diagonally.
