A/N: Hey there!
I know I said I was going to get this done over the weekend, but I realised that it was a very important chapter, so I decided to take a little longer on it to make sure it was at least half decent haha I'm not sure how well that worked, but hey ho... :) I've tried to be sort of equal between the amount of Sam/Lena sibling moments and Dean/Lena sibling moments, but I know I'm seriously lacking with Sam, so I'll try and put more in the next one :D

I know I didn't update Things that Go Bump in the Night this week, but I'm determined to get ahead a little bit more so that I'll have enough to post while I'm doing my exams in January, so I don't want to break into my back-logue of chapters just yet. I promise I'll try and get another chapter up this week :D

Please please pleeeeeaaaasssseee let me know what you think! I love to know what everyone's thinking, and ideas for other chapters are always more than welcome!

Peace out,

P.S. Lena is the same age in this chapter as the last one, but this one is set afterwards :)

Brothers and sisters are as close as hands and feet- Vietnamese proverb.

Dean: 17 years old.

Sam: 13 years old

Lena: 7 years old

As the bell rang at the end of the day, Lena peered out the window net to her desk and spotted Sam, waiting patiently for her with his bag slung casually over one shoulder. He glanced over and saw her looking, so he shot her a smile and a wave. Lena waved back, but she furrowed her brow slightly in confusion.

Weird, she thought Sam never waves.

Dean told her that it was PMS that made Sam so grumpy all the time. She didn't know what that meant, but it sounded serious, so she tried not to take it to heart when Sam snapped at her, and now she was surprised when Sam actually smiled and didn't just mope behind his mop of hair. A few minutes later, she bounded out the doors and down the path towards him. If Sam was in a good mood, she was definitely going to make the most of it, and she slipped her hand into his outstretched fingers.

"You ready kiddo?" he asked casually.

"Yep." Lena chimed. They didn't need to wait for Dean; Lena knew he'd gone to help their father do a job, though Lena didn't know what it was, so Sam and Lena started walking towards the motel. They talked casually as they made their way down the streets. Well, Lena talked, and Sam listened, but that wasn't anything unusual. Sam fumbled a little with the key for the door, but Lena didn't notice as she kept up her almost constant stream of commentary. He let them in and Lena dumped her bag on the bed. She wasn't paying attention as Sam locked the door behind them, a dark, twisted smirk emerging on his face.

Sam hurried frantically down the street. He knew he was almost fifteen minutes late picking up Lena, but his teacher had wanted to speak to him, and the man wouldn't take no for an answer, so Sam figured it would be quicker to just let him talk. However, Sam had noticed that his teacher seemed to like the sound of his own voice, so he'd had no choice but to abruptly excuse himself. Sam knew that Dean had gone with their Dad to hunt down a shape-shifter in the area, so there was no one else to walk Lena back to the motel. He almost ran out of the doors, to see if Lena was waiting for him like she should have been, but the place was pretty much deserted. Panicked, Sam looked around hopefully, but he still didn't see Lena. Although, he did see Lena's teacher coming out the doors, heading towards her car, and Sam jogged over to her. The woman had long dark hair tumbling over her shoulders, and wide, bright eyes that lit up when she gave her ready smile.

"Have you seen Elena?" Sam blurted as he approached, and the grin slipped from the woman's face.

"No Honey." She replied "She left a little while ago, but I thought she went with you?"

Sam felt his blood run cold, and he was sure that his face has paled quite dramatically. He stammered out a thanks to the teacher and took off at a sprint, leaving the woman to stare, bewildered, after him. As he flew down the concrete streets, Sam pulled out his phone and dialled a familiar number, barely having to look at the key-pad to know it.

"What do you want Sam?" Dean snapped after what felt like an eternity of listening to the dialling tone.

"Have you found it?" Sam asked breathlessly, dodging cars as he ran over a road.

"Not yet." Dean replied a little irritably "Why?"

"I think I know where it is."

Lena was watching TV when someone started pounding on the motel door. It made her jump, and she sat for a second with her hear hammering in her throat. Sam was in the bathroom, so she got up and went over to the window, peering tentatively behind the curtain.

She had to blink a few times, sure that her eyes were playing tricks on her. It wasn't possible.

"Sam?" she asked "What are you doing out there?"

"Lena!" Sam exclaimed, spotting her through the window "Where is it?"

Lena frowned at him; confusion etched into her features "Where is what? What are you talking about?"

"Me!" Sam yelled "Where am I?"

"Sam, what are you talking about?!" Lena demanded again, trying to make sense of what her brother was saying to her. Lena heard the toilet flush and the bathroom door clicked open, and Lena felt all the blood drain from her face. She must be dreaming. This has to be a dream. She looked from one Sam to the other and felt the ground hitch below her feet, like it was trying to throw her off. Inside Sam smirked and sneered at her, slowly edging his way towards her. Outside Sam continued to bang on the door and yelled to her.

"Elena, you've got to let me in!"

Lena felt for the door handle with trembling fingers, but when she grasped it, it refused to budge in her hands, locked tight and unyielding.

"Sam, I can't do it!" Lena shouted through the wood. It didn't matter that she was convinced she was dreaming; it didn't stop her from bring terrified. She turned to look at the Sam inside, slowly advancing towards her. Lena screamed when he lunged at her, and she dived under the nearest bed and out the other side. She scrambled to grab the crowbar that Dean kept stashed under his mattress. She had no idea what was going on, but as 'Sam' leapt towards her again, she swung the metal bar as hard as she could, making it collide with his arm. Years of training with her brothers- despite the fact that Lena didn't know what they were training for- had left Lena stronger and fast than her size and age usually entailed, and 'Sam' howled in pain. The sickly sweet, menacing smile slipped from his face, replaced with a glowering snarl.

Lena quickly realised that standing between the two beds wasn't such a good idea, because now she had nowhere she could move to quick enough to not get caught by whatever was standing in front of her. She didn't know what made her so sure that it wasn't the real Sam. There was just something about the way he moved; the way he looked at her that just wasn't...Sammy. Rage made him careless, so when he went to grab her again, Lena lashed out with the crowbar, this time making contact with his head. He stumbled for a second, caught off-guard by the blow, but Lena hesitated too, shocked by what she was doing, but it was as long as he needed to whip the bar from her hands.

Her fingers resorted back to trembling. She backed up as far as the furniture would allow, but it wasn't far enough. She was trapped, and the boy in front of her twirled the cool metal mockingly between his fingers.

Wake up now Elena, she thought desperately, Wake up now El-

The door crashed open, almost thrown off its hinges by two, big, heavy boots.

"Elena, get down!"

Lena reacted immediately to the familiar sound of her father's voice, and she ducked to the floor, throwing her hands over her head instinctively. She squeezed her eyes closed tightly, determined not to see whatever was going to happen next. A few loud bangs cracked through the air, and less than a second later, there was a thud right next to her, but Lena still didn't open her eyes, couldn't open her eyes. Lena whimpered a little when a pair of strong hands bundled her up, and she buried her face into the worn material of her dad's jacket. She clung to him fervently, seeking comfort and solace in the musty leather. She felt her tears soaking into John's shoulder as he muttered soft assurances into her ear, telling how well she'd done, how brave she'd been, but Lena had never felt so scared. She barely heard as John told Dean and Sam to get rid of 'it', but she heard her brother's grunting under the strain of lifting whatever 'it' was. A minute later, the door clicked closed, and they were gone.

It was almost two hours later when Dean and Sam let themselves back into the motel room. Dean had angrily grilled Sam about being so careless, but deep down, he knew it wasn't the kid's fault. He just needed someone to be mad at. And he knew that nothing he could say to Sam would make him feel any worse than he already did. Streaks of guilt were present behind Sam's eyes, and as soon as Dean realised that everything he wanted to say to his little brother was accusing, he just remained silent.

They'd driven for twenty-five minutes out of the town they were staying in to find somewhere to burn the shape-shifter's body. The town was so small and isolated that they needn't have gone that far out to be completely deserted, but they had to be sure that they wouldn't be spotted burning a body.

It was silent when the brothers walked into the motel room. The TV was switched off, and John was sat at the table, cleaning a gun. He looked morose as he glanced up at his sons, but he didn't say anything. Lena was sat, cross-legged, on one of the beds with the earphones for Sam's walkman pressed into her ears. Her eyes were in her lap, and she still sniffed slightly, but she wasn't crying anymore at least. Dean perched himself on the edge of the bed next to her, but when he tried to wrap an arm around her shoulders comfortingly, Lena shrugged him off and turned away. Dean mentally groaned; it was clear to both Sam and Dean that Lena now knew about 'the family business' and no matter how hard he tried, Dean couldn't work out exactly what was going on in his little sister's head. She glanced at him momentarily as she got up and went to the bathroom, gently closing the door behind herself, though it rang louder than if she had slammed it shut.

The innocent sparkle was gone from Lena's eyes, and Dean knew that it wasn't coming back.
