Chapter 5

Dean yawned and stretched, knowing form the heat he could feel that Sam was curled beside him. Sam seemed skittish whenever Dean got too far away so Dean had simply started getting them rooms with a king sized bed. Sam was like his own personal hot water bottle and it was nice though he figured he wouldn't be so happy about it in summer. He'd thought Sam was sick when he'd first noticed but Sam had explained that wolves ran hotter than humans, not to mention the increased appetite. Sam used to stick to what Dean teasingly referred to as rabbit food but these days he ate what Dean ate, lots of meat and Dean figured it made sense, wolves were predators after all. He was still coming to terms with the fact that Sam wasn't human anymore but wasn't anything like the beings he hunted. He turned his head to see Sam sleeping beside him and smiled at how innocent Sam looked in sleep, the bruise caused by the ghost throwing a lamp at Sam's face already looked days instead of hours old and that was a relief. He hated it when Sam got hurt and he knew Sam hadn't hunted in years. Dean watched as Sam began to wake up, eyes slowly opening and then focusing on him and Sam smiled. "How's the face?" Dean asked and Sam grinned.

"Fine Dean, I heal fast these days. Don't blame yourself for it either, I chose to distract it so you could find the locket and burn the hair." Sam answered and Dean sighed but nodded. "So what's next?" Before Dean could answer his phone rang and he grabbed it and then glanced at Sam. "Dean?"

"Dad." Dean answered and Sam paled.

"Please, don't tell him I'm here." Sam whispered and Dean stared at him before nodding. Dean answered and Sam rolled onto his back, able to hear both sides and wincing when their Dad berated Dean for taking so long to handle the hunt. Dean saw the wince and moved his free hand to run through Sam's hair, making him smile and relax. "I'm sorry Dean, he's mad at you and it's my fault." He whispered when Dean hung up.

"Hey, it is not your fault. I can handle Dad." Dean assured him and Sam stared at him before finally nodding and moving so his head was on Dean's shoulder. "So you gonna tell me what's going on yet?" Dean asked softly after a while of just lying quietly. He felt Sam tense and wrapped his arms around him to keep him form bolting. "Sammy I will never kick you out, you're my baby brother." Dean promised.

Sam turned in Dean's hug so that he could look him in the eye, terrified that would be one promise Dean couldn't keep. Finding out about Imprinting could ruin everything and Sam couldn't lose Dean again.

Dean saw the fear in Sam's eyes and hugged his brother tighter. Why was Sam scared? What could those Elders have possibly told him? "Sam? Are you okay? You're not sick or…are you?" Dean demanded and Sam shook his head. "Then why are you scared? We've already done the show and tell and I'm not scared of you Sammy, so what could be harder to tell me?" Dean asked and Sam sat up, breaking Dean's hold easily. Dean watched as Sam moved to sit with his legs over the edge of the bed, head down. "Sam?"

"I….I imprinted on you." Sam whispered and Dean frowned in confusion. Imprinted? Wasn't that what baby animals did to their parents or something?

TBC….

Very short I know but I can't decide how to have Sam explain it or how Dean should react to suggestions please!
