1.- Holding hands

Personal space was a long forgotten rule to Cas and Dean. And of course, in the middle of it, the lack of space between them had became into rubbing and touching. Arms touching while sitting one next to the other, general rubbing when they walked next to each other, without noticing an absolutely empty room where they could walk without even notice the other.

Sam just rolled his eyes and smiled softly.

"What? What am I missing?" Jack asked, one day, Dean and Castiel kept bumping into each other in the kitchen.

"Uh...? Nothing... No, did you finish your breakfast?" The youngest Winchester said, avoiding call his brother's attention.

"Yes. But-" Jack replied while Dean and Castiel sat in front of them.

The angel was holding just a cup of coffee, while the human had a plate full with eggs, bacon, toast and some cheese.

"Then, if you're ready, come with me to the library" Sam said, taking his and Jack's plate with him to let them on the sink.

Once they were outside the kitchen, Jack asked again. "Seriously Sam? It's everything ok between you and Dean? Because you always leave him alone with Cas, and avoid to looking at them when they're talking... Can I help somehow?"

Sam considered the idea for a second. Yes, the kid was really smart, but he was like two years old and there were a lot of things he needed to understand before explain him what he was thinking. Besides, he wasn't sure yet about whatever the hell was going on between them.

"I just think Dean and Cas need time alone. You know, like... do things by their own." Sam explained. And then he added in a whisper "And to figure out their feelings" But Jack didn't listen.

Jack found them a Sunday afternoon in the recreation room. They were watching and old western, well, Castiel was. Dean had his head on the angel's shoulder and the Nephilim took a couple of minutes before notice he was asleep. The truly remarkable thing was that when he approached to talk to Castiel, he saw Dean's hand on his father's leg. Cas's hand next to it. They both spoke in whispers, without waking the hunter up. Jack left the room thinking about what he had witnessed. Maybe Sam was right, maybe Dean and Castiel needed all the time they could get.

The first time Dean and Cas hold hands was during a hunt. They were after a pagan God, and just like Sam said, Castiel was just a seraphim, a God would kill him easily. So, when the plan failed, Dean grabbed the angel's hand and run with him until they reached Jack to take down the divine entity. They kept their hands together until Dean was able to breath normally again. Even then, they let go slowly and Cas wrapped an arm around Dean's waist, you know, in case he felt dizzy or something.

The second time, they were watching a movie, alone. Their fingers interlaced for the two hours of the film. But they weren't supposed to talk about it.

The third time, they were outdoors. Outside a gas station, on their way to a Metallica concert, Sam and Jack were teasing Dean about how he had run from the Pagan God.

"Dude, I've been tortured, punched, killed and cursed by those sons of bitches. I'm done with them. Besides, the kid got him pretty good." Dean defended himself.

"Of course it was thanks to my instruction, because if he did what Sam said, we both would be dead by now." Castiel declared, deadly serious face.

"Yeah, that!" Dean said, and pointed at Sam "Suck that, Sammy!" He held his hand on the air "High-five, Cas!" The angel looked confused. Dean rolled his eyes "Just... like the movie we watched the other day, remember?"

"Oh." Castiel said, as the memory came to him.

Now, it's not clear what part of the movie Cas thought about, but the thing is that he highed-five Dean, but instead to take his hand down immediately, he just kept it there. Dean looked at him, a little tilt of his head. Then, their fingers found their way into each other's hand. Dean smiled shyly and sighed. Still with Cas's hand in his, he put them both down. After all, if they were going to start holding hands and all that, better not showing off by having them up all the time, right? He gestured the others to follow him to the car and glanced the proud smile on Cas's face while they walked. It could be something easy to get used to. So, he just rolled with it.

And well, Sam and Jack kinda rolled with it as well.
