Sirius stood watching the smiling laughing faces dance around him. He stood in the center of the dance floor, looking for Remus, or James. Someone to show him that he wasn't there alone.
"Why the bloody hell did I come here alone? I can't do this! What if I see Willow before I see James or Remus? Damnit Autumn, you talk about deserting friends when they need you…"
He spun slowly scanning the faces of the people dancing around him. He stopped when he thought he saw someone that wasn't supposed to be there. The song ended and the crowd drifted off to get some punch or look for friends and he realized it wasn't Lily that he had seen.
Autumn stood twenty feet in front of him and had obviously spotted him before he had her. She was dressed in robes of black with pink trim and when the lights moved he saw that there were pink stars that glistened when hit by direct light. He ran to her and hugged her. When she didn't return the hug he backed away from her looking at her questioningly.
He then saw that she had applied makeup, but at some point between the application and her arrival her tears had destroyed it and there were long black streaks that ran the length of her face.
"I didn't want to abandon my friends." She said softly.
Sirius leaned in and kissed her cheek gently. "You're the best sister a guy could ask for, and you look beautiful."
Remus had been trying to enjoy himself as much as possible from his corner of the ballroom. He had some trouble as Silver was constantly bothering him to dance with her. Just as she walked away complaining that he was a horrible date and she was going to find someone else he spotted Autumn walk in. He watched her and when his view became obstructed he began to follow her through the crowd. When he saw Sirius lean in and kiss her on the cheek he was filled with rage and began to run towards his friend.
Willow only saw Sirius kiss Autumn when Snape turned her around and told her to follow him.
In the mess while Remus was on top of Sirius trying to kill him, Autumn looked up and saw Snape and Willow exiting the Great Hall. She knew something was wrong as seconds later Malfoy and a group of other Slytherin boys followed them. She stood confused as to whom she should help and decided the boys could work things out on their own. And Just as she ran out the doors to the Great Hall she collided right into Malfoy's back.
"Well hello there. I see you've come to join your little friend. It turns out you will be of great service to us Slytherins after all." Autumn was grabbed by two larger boys and was carried away as she kicked and struggled against them.
"Malfoy we can't hold onto her much longer!" on of his thugs said as he strained to hold onto Autumn. Malfoy simply turned and hit her with the leg-locking charm and she remained still. She began to scream and was struck with a silencing charm as she was picked up and drug down the hall against her will. "Now will you two please hurry up, we don't have much time to get to the astronomy tower." Malfoy said as he took the lead.
Aurthur Weasly chose to remain silent as he watched Autumn from afar. He figured that he couldn't take Malfoy and his goons on his own.
Sirius had no idea how he'd ended up running to the astronomy tower with James Remus and Aurthur. He vaugley remembered Aurthur mentioning seeing Autumn being attacked when he was on his way back from the toilet. He remembered James and Lily trying to pull Remus and Sirius apart, having very little success, but as soon as Aurthur mentioned that Autumn and Willow were in trouble the spat was forgotten and the two lead the way to the upper most tower of the school.
Autumn for a moment thought of transfiguring herself to escape, as she could do it without having to move or speak. But there was no way that her secret would be kept by the Slytherins.
