Hello, I'm feeling a little bit lazy and don't feel like talking much.
The Winchesters are sitting in the car, bracing themselves for the battle they would be facing. Cas had already gone ahead to fend off the group of demons who have started to wreak havoc in the area. They apparently are planning something and they need to put a stop to it. It almost feels like the apocalypse again. They hear the sounds of struggle from one of the houses they parked in front of. That is their cue.
"Mary, I need you to stay in the car," Dean orders. "No matter what you hear, what you see, or who comes to the car. Keep the doors locked and stay quiet, you hear me?"
Mary nods, too scared to utter a word. Against Dean's will, Mary is slowly being dragged into the reality of this dark, dangerous world. Even as he denies it, he knows that soon he would have to teach her to fight and shoot a gun. Maybe he has to teach her how to keep safe, but no way in hell would he ever let her go to the frontline. That is the one promise he holds to himself.
They hear the scuffle of fighting and take it as their cue. They let themselves out of the car and Dean slides his knife into his belt beside his gun, lugging the duffel over one shoulder. They leave Mary in the car with mere centimetres of air ventilation. If there was a better option, Dean would've taken it but there isn't.
"Mary, lock the doors and don't open it for anybody," Dean instructs one last time before walking towards the houses at the end of the road. "Sam, I'm going in," Dean continues. "Stay in sight of the car."
"But Dean –," Sam tries to argue but is cut off.
"I need you to take care of Mary," Dean explains roughly. "Guard the car. Go, now." He doesn't wait for Sam to respond before charging straight into the thick of the fight.
Demons are all over the place, it looks as if the entire neighbourhood decided to meet up in this one house. Then again, they did. The demons do not notice Dean coming in as they are all too busy dealing with the angel who is smiting two demons for every one that comes within reach. The source of all the demons are anybody's guess, they seem to just appear out of nowhere. Dean sneaks a can of salt out of is duffel and line the entrance with a thick line of salt. He skirts the perimeters, leaving a trail of salt behind him. It's startling how none of the demons even realise he's here. Their duty tonight is to get rid of the demons and keep one or two alive for questioning.
Emptying the last of the salt, Dean takes a readying breath before yelling, "Hey, dickheads!"
All the surviving demons in the room turn to him, visibly snarling in a way more suitable for a vampire than a demon. In less than three seconds, they pounce on him only to be stopped some invisible barrier holding them back. They look around for the devil's trap and find it above their heads, taking up the entire ceiling. He can't help the smirk that crosses his face when he thinks about their ignorance.
"Now, since we're all gathered here tonight, we might as well get to business," Dean announces. "So," he claps his hands, "who wants to go first and tell me what you're after?"
He doesn't get his question answered as the front door bursts open and Mary stands there looking for Dean. She spots him across the room and she makes her way over to him before he could even tell her to stop. Dean watches painfully helpless as Mary steps into the far end of the circle.
"Mary, I need you to step back," Dean orders firmly.
Mary is scared, Dean sees that, but his need to get her out of danger overrides all sympathy and the only thing he feels now is anger and frustration. Mary is lost, bewildered and desperate to get to her father. She stands frozen at the edge of the trap, unsure of what to do.
"Mary, get OUT OF THE CIRCLE," Dean yells.
The demons turn their attention to the defenceless little girl and Dean stabs the one closest to him before she could even think of touching Mary. The fight starts and Cas tries his best to fend the demons of Mary as Dean slowly makes his way over, killing every demon in his way. Only then does Sam appear at the door out of breath and with worry etched all over his face. He sees Mary cowering behind Cas who has positioned the two of them into a corner to keep Mary safe. He sees Dean with a vicious glare in his eyes as he fends off more demons. The demons are still trapped in but they are using physical weapons to make up for their crippled powers.
"Cas, blow this place up," Dean yells.
The angel obeys, telling them to close their eyes before emitting blinding white light all around the room. From outside, the house windows spill with Cas's pure white power. When it fades, Sam and Dean blink out the dark spots from their retinas. Dean recovers first and runs over to where Mary is curled up and crying. He checks for any injuries and is relieved that she has only escaped with small scratches. He collects her up in his arms and whisper soft words to her.
"Shh, it's okay. They're gone, it's okay," Dean says repeatedly, punctuating with kisses on her head. "They can't hurt you anymore, it's safe now. It's okay, honey, it's okay."
"Dean, I'm sorry," Sam says.
Dean looks up at him with accusing eyes. He hands Mary over to Castiel to make sure that she's a hundred percent alright. "Where were you? I told you to keep an eye on the car!" Dean is livid and Sam takes a step backwards in fear. "How in the hell did she get out of the car?"
Sam holds his hands up in a gesture of defence but Dean doesn't let up. Sam has seen him get angry over people harming his family, but he has never been on the receiving end of it. "There were two demons out there, they were attacking the car. I tried to get rid of them and she got out of the car and ran," Sam explains. "By the time I was done with the demons, I lost her."
"You lost her? You lost her! That's great Sammy," Dean says sarcastically. "She could've been killed!"
Sam hangs his head low, knowing nothing will calm his brother down when he's in a rage. Then again, it was also partially his fault. He should've kept a closer eye on Mary and kept a better guard. If only he were as good as Dean.
"Dean," Cas says softly. "It's not his fault, the girl is scared and the first thing that comes to any child's mind is to look for their parents," he explains.
Dean's shoulders relax just the smallest bit and he says, "C'mon, let's go."
Special thanks to Priya723 for the idea of Dean getting angry at Sam for getting Mary into harm's way. I apologise if it's not satisfying as I find it doesn't quite fit the bill but I really need to post something and get the guilt out of the way. Also the latest episode of Supernatural made me sad and moody.
