She would do it tonight.

She had done some digging, and this boy, Gavin by name (Ivy didn't really care about his name), had a room all to himself.  His room was nearby, room 109.  She'd have to keep him quiet, however, as there were people all around his room. 

Autumn was sleeping at her friend's dorm, Cynthia or something like that, and would be far away for the night. Normally, Ivy would be upset by this, but it gave her the perfect opportunity to right a wrong. For that reason, she didn't mind.  Although, she would have to keep an eye on Cynthia.  She could be an obstacle, and Ivy couldn't allow anyone to get in her way. 

Ivy packed her backpack, and slid the knife, so the blade was facing her hand, down her sleeve.  In her bag she had cleaning supplies, a change of clothes, a lock pick (she hoped she didn't have to use that), and an extra knife, just to be safe.  You never know.

Making her way down the hallway, Ivy thought her plan over in her head.  She thought all day on it, but there were still so many things that could go wrong.  He could deny her entry, or he could scream, if she wasn't quick enough.  That part worried Ivy the most; she'd never have a chance with Autumn then.  She planned to pretend to confess her feelings for him, and while he was surprised, she'd slip her knife into her hand, and stab him, killing him before he could scream.

She reached his door, and, taking a deep breath, knocked lightly. A groggy groan called out, and he soon was at the door. He clearly was half asleep, so perhaps she wouldn't even have to pretend she liked him. "Whatzit?" He yawned, sleep blearing his eyes.

"C-can I...come in? It's important." She looked down, pretending to be nervous, as he nodded, opening the door more. They went into his room, and while he was still walking with his back to her, Ivy slipped the knife into her hand, and sent it straight into the vein in his neck. He collapsed, blood everywhere. On the floor, on Ivy, on the wall. She had a lot of cleaning ahead of her. Getting out some hydrogen peroxide, she started dumping it everywhere there was blood, and soon the blood was mostly fizzed away. She scrubbed away the remaining blood, and dragged the body under his bed. She changed quickly, stuffing her bloody clothes into the back pack.

She put everything back into the bag, and ran as quickly and as quietly as she could, hoping no one heard her. Sh'd have to burn the clothes, and find a place (far away, preferably) to bury the knife. For now, though, she was satisfied with her work, and took a moment to revel in her victory, before exiting again to dispose of the evidence.
