"Are you sure, Dean?" Sam asked, his silver blade hanging loosely in his hand. "We should have let Cas come."

"No," Dean said with a shake of his head as he picked the lock to the library.

"Are we even sure it would be here on this campus?" Sam asked and spread his arms out. "There are a lot of other college campuses that the werewolf could be on."

"Do you doubt my ability, little brother?" Dean asked and stood up, opening the door to the library.

"Why would it even hide in the library?" Sam asked crossing his arms over his chest, refusing to go in.

"I was in here earlier today," Dean said sighing. "There are scratches in one of the closets on the second floor. If that doesn't scream werewolf, I don't know what does." He then walked inside quickly and Sam followed hot on his heels.

Dean drew out his own silver blade and tested the weight of it in his hand as they made their way up the stairs. Sam had pulled out a flashlight, lighting there way as they came to the second floor.

"What closet was it?" Sam asked, cascading the white light across the shelves of books.

Dean chuckled slightly as he called out, "Here bitch!"

"Dean!" Sam snapped and grabbed his arm in a tight grip. "Don't we want the element of surprise?"

"Who cares?" Dean asked and pulled his arm from Sam's grip and began to make his way around the second floor. He crept his way around until he heard Sam grunt. "Sam!" Dean called out and turned to go back, but Sam was thrown into Dean.

The two of them fell in a heap on the floor as the growl came from the monster. Dean was the first one up and saw that the monster was a female, an obviously pregnant female. This was the part of his job that Dean hated the most. He hated having to kill the monsters that had baby monster inside of them that had yet to do something bad.

The female growled low at Dean, baring her sharp teeth. He knew she was going to protect her young till the end, so he prepared himself for a fight.

"Come on," Dean said and bent his legs slightly.

The female growled and charged Dean. Dean stepped out of the way, slashing the blade across her back. She cried out before turning and clawing his chest. Dean grunted as thick bubbles of blood began to come from three scratches on his chest. He stumbled back away from her next swipe that was coming for his neck.

Suddenly she was sent to the side when Sam tackled her. The two of the rolled on the floor, but she had easily mounted him, ready to slice across his neck. Dean pulled out his gun and shot her in the side, wounding the powerful female.

Her anger was quickly directed at Dean, giving Sam enough time to plunge his knife into her heart. She grabbed at it, taking in a sharp breath before her eyes rolled back. Sam shoved the limp body off and looked to Dean with a goofy grin on his face that quickly turned to a look of pure horror.

"Her mates behind me, isn't he?" Dean asked, his face turning into a grimace.

A sharp outtake breath on the back of Dean's neck answered his own questioned and he slowly turned around to face the large werewolf. He was inches taller than Dean and probably taller than Sam. He growled before bringing his claws back and swiping them towards Dean, who quickly jumped back despite the blood still coming from his first wound.

"Dean!" Sam shouted and tossed his older brother his blade.

Dean caught it easily, stepping back away from the angry male until he knew he had the upper hand. "Come get me," Dean said and flipped the blade around in his hand.

The male was too entranced with how the blade moved around in Dean's hand to pay any attention to Sam coming up behind him. Sam grabbed the massive man with a vice-like grip and Dean lunged forward. The werewolf twisted himself so the blade only got his stomach. He grunted before pulling his arms from Sam's grip and punching Dean in the face. He turned quickly and shoved Sam back into a huge bookcase.

The bookcase wobbled as Sam fell to the floor. Dean saw the bookcase falling and moved quickly, catching it. Books cascaded down onto the two of them, creating new bruises with each hit. His muscles flexed trying to hold up the heavy bookcase.

"Move, Sammy!" Dean snapped as his arms began to ache.

Sam had just started to move when the werewolf tackled Dean to the side. Dean watched in horror as the huge bookcase toppled over with his little brother lying underneath it.
