The Common Room;
Lily had been patrolling, muttering about James' irresponsibility (he had forgotten to, or, more likely, simply decided not to come), when a large spell had sucked her in. She felt something yank on her navel as if she were using a Portkey, and colors and numbers whirled her up, set her down, then spun around her. When they abruptly disappeared, she looked around, breathing heavily. Everything still looked quite normal. She thought she knew exactly who was responsible for this prank. She had been terrified, but now she was just angry.
"POTTER!' she screamed. Lily marched up to the common room, grumbling. The portrait swung open to admit her. She stormed in.
"Potter, you low-life, that's a horrible example to set; you're Head Boy! I'll…" She drifted off, noticing that James wasn't there. A redheaded seventh-or-sixth-year had his arm slung about his girlfriend as they cuddled on the couch. Remus was sitting in front of the fire, reading, and Peter was trudging up the stairs to his dormitory. At least, that's what they had been doing; each and every one was now frozen, staring at her.
"Um, sorry, didn't realize; thought Potter was here. Horrible spell caught me in the corridor-it was him, I know it." She mumbled, turning faintly red.
To her surprise, so did the redhead, and Remus paled slightly. Red's girlfriend leaned over and began frantically whispering in his ear as he frowned ever so slightly.
"'Mione, you sure?" he asked softly. She inclined her head, and then glared at him.
"When's the last time you remember me being wrong?" she demanded.
"Uuum, third year. The broomstick. Then again last year, I s'pose, about Snape," he told her, then sighed as Lily watched interestedly. He turned to her, keeping his arm around Girlfriend's shoulders. "Are you Lily Evans? Do you know where you are?"
"Yes, and I'm in the Gryffindor common room."
"Ron, you idiot, you should have asked her when," GF teased. "Listen, the Marauders came into the future, and it seems that you were caught up in their spell." At this, Remus and Peter simultaneously bolted; Peter up the stairs, and Remus out the portrait hole. Lily looked at GF, not believing a word she said.
"Where are the rest of the Marauders?" Lily asked, eyes glinting dangerously. She heard someone cough in the corner behind the couple's couch. Angrily, she strode over, and heard muffled scuffling and words as she did. Then she hit something.
The cloak slid off, and James smiled weakly as the other two boys cowered behind him. "Hello, Evans."
