Merthur/Merlin one shot

Merthur, Winchester Brothers can just end up in chaos part 6 of 7

Arthur's Pov

They ended up going on a hunt and he really was curious what they planned on showing him. There was a reason why they took him. The reason soon was clear when they started to tell him something that he had not expected the first meeting of the two brothers. (I will make a separate chapter of their first meeting)

Now he knew why the two were so protective and the trip went well. Sam was the one who had been the one who actually had smacked him behind his back for what he had said. But could he blame him for being pissed at Merlin?

The moron had hidden this secret the entire time but more than pissed he was betrayed and hurt by him hiding his magic. Yes, he was taught that magic was evil, but he knew Merlin and no way in hell could Merlin hurt a fly.

The moron was the clumsiest, kindest and cutest person he has ever met. God knows what his father had thought of magic was evil. It can corrupt yes but Merlin is the best example that magic can be used for good.

As he was pretty sure that the idiot had been the one who had helped behind their backs many times. No wonder they survived that often and him disappearing to get drunk was not true. It was something that Gaius just choose to make him not suspicious.

Now he felt bad for him yelling at Merlin. God they will need a long talk but for now he would need to get the little to trust him. Not an easy feat with how he treated the adult version. A heavy sigh went out and it was obvious that the two brothers were still not pleased by what he had caused.

"Look I can understand why you said these things but dude you went too far. Merlin never wanted to do any harm. The moron is too soft to harm something. Heck every time we go on a hunt he looks like a kicked pup when he has to kill something." Dean huffed out and amusement, yet fondness was also seen.

"It's thanks to him that we had survived that long and I do want you two to make up."

"This is why you decided to drag me with you two to make me understand but why a hunt? Surely there would had been better places than a place littering with creatures?"

He couldn't help himself but mention this. The two had eye contact for a moment before answering the same time.

"Because you're also a hunter and tried to find out what was going on in that school."

This was making him chuckle and giving a shrug as it was true. But how they knew he couldn't really guess but then again he had used the shotgun with precision so maybe this was why.

"Yeah, yeah you got me there. Could we go back, kind of want to meet little Merlin and make sure that he understands that I am not mad at him anymore."

"Good or else we would have to kick your ass."

"Sammy really?"

"Oh come, as if you wouldn't had said and do this then and also don't call me Sammy.."

The two continued to bicker about this and he let out a heavy sigh. This reminded him of the time where he argued with Merlin. The same playfulness that the two had and he kind of missed the moron now. When they ended up entering the bunker one of his eyebrows went up when seeing the chaos that was.

There were many colorful things drawn on the walls and he wasn't surprised at all. This seemed the kind of thing that Gwaine or Merlin would end up doing.

"Gwaine and Merlin come here now!" Lancelot's voice sounded frustrated and there were giggles and one person snickering. Yup definitely the two troublemakers.

He remembered how much chaos the two could cause and he felt fondness bubble up. This was the thing that he had missed. God these two were impossible but he also couldn't help the fondness that grown.

"Well guess Merlin did cause you trouble huh?" Dean mused out loud and Lancelot turned his head, and his gaze went to him. It was the kind of gaze that was given to him to help out. He chuckled as sneaking around and when entering the place that the two were hidden he snorted.

Merlin's hands showed evidence that he had been the one who colored the walls. Gwaine looked at him with a look that showed 'shit I have been found,' and this alone made him raise his eyebrow on the other.

"You are the adult and should have stopped Merlin." The tone was stern and Gwaine looked at him with these innocent eyes.

The kind of eyes that made him feel him get into his caregiver instincts. He always had the feeling that Gwaine might be a little and seeing him like this made him know that he was maybe 5 years old. Maybe even younger.

"Please no one got hurted and we just wanted to have fun. It was boring." Even the tone was showing him that the other was younger. Well at least he knew now why Gwaine always had that longing look when looking at the little things that he bought.

"I know but you made a mess and caused trouble. How about you go and apologize to your Daddy and clean the mess up?"

"But..."

"Gwaine no buts." He made sure to make the tone soft but there was also the firmness that made the other know he won't budge on this. So, with a pout Gwaine left. Now he was alone with a little Merlin who looked at him with big fearful eyes. But there was also the longing one that he realized.

"I am not mad at you, but you have caused a lot of trouble for your big brother Lancelot." He plopped himself down as giving the other and fond look. "Then again wouldn't be you when you would not cause trouble." The amusement was more seen, and Merlin watched him closely.

His head titled and he knew that the other would not understand what he meant. Meaning that he would have to wait for the other to get back on his own to his age.

"Well let's get you cleaned up, huh sunshine." He mumbled this to himself and he couldn't help but chuckle in amusement when hearing giggles slip out. At least Merlin seemed to be a bit less tense. So, he careful picked the other up.

Weirdly enough he wasn't heavy. It was as if Merlin was from the weight like a baby. He could just think that the other used some magic to make him lighter. It was helping a lot. The mentioned little was tensing up but soon leaning into the touch as snuggling into his arms.

"Dada?" The soft question made him come out of his musing and he glanced down to see big innocent looking eyes wary yet also questioning.

He could just guess that the other was not knowing why he was helping out. It made him smile softly and he was pretty sure that Merlin was still thinking that he was angry about that secret that he had hidden.

"Not mad sunshine about that secret. We will talk when you're your age okay?" His voice was soft, and he made sure to make sure that the other understood this.

This made Merlin blink and giving him a beaming smile. God he was adorable, and he would make sure to protect Merlin at all cost when he was in this state. Soon he was in a new onesie and the rest of the day was with him having to cuddle Merlin as the little wasn't wanting to let go. Not even for his Papa.
