The first years walked into the Great Hall, following Professor McGonagall. James tried to stay close to Lily, but Lily kept going further away from him. The hat sang a song, as usual, and then the sorting began. There was nothing special to the sorting.
Bellatrix Black-Slytherin
Sirius Black-Gryffindor
Lily Evans-Gryffindor
Malfalda Hopkirk-Ravenclaw
Frank Longbottom-Hufflepuff
Remus Lupin-Gryffindor
Marlene McKinnon-Gryffindor
Severus Snape-Slytherin
Peter Pettigrew-Gryffindor
James Potter-Gryffindor
Alice Pruwitt-Hufflepuff
Emmeline Vance-Ravenclaw
There are others, but I won't list them for my own reasons. Marlene isn't supposed to come until a year after Lily, but for plot purposes, I'm making her come in now.

After getting sorted, Lily sat down at the Gryffindor table. She was releived she didn't get into Slytherin, but the hat wanted her in it. She sat quietly for the sorting to finish.
After Remus was sorted, he sat across from Lily. Marlene sat next to Lily. Sirius, too, sat next to Lily. Peter sat next to Remus, and James squeezed in between Lily and Sirius. Lily rolled her eyes after James sat down.
"Hey Evans." James said, smirking.
"Potter." Lily said, not looking at him.
James put an arm around Lily's ahoulders again. "Isn't this great?" He asked smiling.
"Isn't what great?"
"Being in the same house of course. We'll have all our classes togather, we'll sit at the same table when it's time to eat, and we'll be in the same common room."
"Oh yeah. It's just wonderful." Lily said sarcastically.
"I know. I can't wait for this year to start." James said, pulling Lily closer to him.
Marlene was laughing softly at Lily and James when Lily gave her a pleading look. Lily and Marlene met each other on the boat ride to the castle. Lily had managed to get away from James for that ten minutes of the night.
Sirius, however, was smirking at James and Lily. James was acting weird, but he would figure out what that was later tonight. So, he just went along with it.
Alice was looking at Lily sympathetically from the Hufflepuff table. She was sitting next to a guy Lily nor Alice knew. Lily smiled softly to ease Alice (She was looking shy). While Lily and Alice were exchanging a conversation without speaking, James still had his arm around Lily's shoulders and was talking to her, but she wasn't listening. Alice looked down, and Lily turned towards James to see what he had been talking about.
"...and then I took the quaffle from Sirius and zoomed past everyone on his team and scored. 10 pointes to James's team!" He said.
Lily rolled her eyes at both James and Peter. James was here talking about himself to Lily, who wasn't listening, and Peter was looking at him in awe.
Sirius was looking defeated. "You only got the quaffle because I was caught off guard." He defended himself.
"Keep telling yourself that, Sirius."
Lily shook her head at the guys, then turned to Marlene and started talking to her.

After the feast was over, the first years followed the Gryffindor Prefects and the head girl. They said what the password was and explained the dormitories. Lily went right upstairs with Marlene and the rest of the Gryffindor girls before James could get a chance to find her.
"Ugh!" She said, falling on her bed. It was their first night here and Lily was already fustrated.
"Oh come one, Lily. He's not that bad." Marlene said.
"Easy for you to say. He's not always sitting next to you and putting his arm around you."
"Lily, it sounds like he fancies you. I would kill for someone as good looking as him to fancy me."
"But, he's not good looking."
"He is a little." Marlene blushed a bit.
Lily noticed the blush and laughed softly. "Then, why don't you go out with him?" She asked.
"Because, Lily, he doesn't fancy me. He fancies you."

"James, mate, what was up with you and Evans?" Sirius asked up in the boys dorm.
James smiled when Sirius mentioned Lily.
Sirius noticed this smile. "Oh no, mate. You don't...Do you?"
James nodded. "Sirius, I am in love with Lily Evans."
Sirius fell onto his bed dramatically. "I've lost my best mate." He got up and ran over to Remus. "Remus, buddy, you're all I got. Don't lose me either."
"Well, Sirius, I think it's good that James likes one girl and not many."
Sirius fell to his knees dramatically. "NOOOOOOOOOO!" He said. "I've lost James and Remus...Petter, old pal, what do you think?" Sirius said, looking at Peter.
"I...agree with Sirius." Peter said. "No one took his side, so I will."
Sirius nodded proudly. "This boy standing beside me, is the only sane person in this room, besides me of course."
"Well, you can't blame me." James said defensively. "She's beautiful. With her deep red hair and stunning green eyes. Who wouldn't love her?"
Sirius just shook his head doubtfully and climbed into his four poster bed that was next to James's. "I've lost you..." He said, before closing his eyes and falling asleep.
James laughed softly and fell asleep as well.
Remus and Peter too fell asleep.
