Lisa/Justin (sort of, more like friendship)

"Don't you dare put that there! And stop crying, too."

I don't own Harry Potter.

"Please Lisa, for the love of Merlin, just set down the book and come to dinner."

Lisa shook her head, tears dripping down her cheeks as she wrenched her eyes from the book to Justin. "But Justin-" more drops bubbled down her cheeks. "F-Fred just d-died! G-George and P-Percy watched it and-"

She sobbed loudly and buried her face in her arms. "My life is a lie!" she cried, ignoring the looks of the other patrons of the library.

Justin awkwardly patted Lisa on the shoulder, and tried to grab the book from the hysterical girl. He did so rather easily (much to his surprise, the girl had a tight grip on it, so he was rather proud of himself at that moment), before shuffling over to one of the random bookshelves and shoving it in.

The Hufflepuff turned around and was about to head back to Lisa, but Madame Prince descended on him like a hawk on its prey.

"Don't put that there!" she screeched, flapping her old pruned arms like wings. Madame Prince grabbed the book and held it close to her chest. "And stop crying, too." She glared at Lisa, who was bawling quietly into her hands, and stalked towards her desk at the front of the room.

Justin sighed in relief when Madame Prince turned a corner and wasn't visible anymore.

"Come on Lisa, we should go before Madame Prince gives us detention for breathing, or what not." Justin rolled his eyes, and grabbed Lisa's shaking shoulder, awkwardly wrapping an arm around the quaking girl.

"Let's go, I'll get you back to your Common Room where all of your friends have probably read the book also and are crying their eyes out…"

The brown haired girl threw her head to the side to look at Justin's pale face. "Percy- Fred- George- Sirius- Dobby- they all died and you don't even care!"

Justin nearly jumped at the sudden words and movement. "No, I do care, it's just that all of these characters are fictional. Fictional, Lisa."

"And what happens if we are just fictional human beings being written out by an author at this given point in time?"

Justin blinked. "I doubt that, Lisa."

He pulled her away from one of the suits of armor, and barely avoided tripping on a loose piece of thread from a carpet- or was it a curtain? He couldn't tell.

Before long ("Oh thank heavens," Justin said when he saw the familiar knocker on the wall. "I thought we'd never get here.") Justin was able to pry Lisa off of him and shove her into the Common Room, where like he had predicted, almost all the Ravenclaws had the book in hand and crying their eyes out.

Justin walked away feeling like he had done the good of society that day, for reuniting one nerd with another.

A week later had him bawling like crazy as he yelled, "F-Fred, G-G-George, P-Percy- WHY!?"

Lisa approached him in the library and said, "I told you so!"
