Castiel's Little Sister SPN

Meeting Dean

I stand behind Castiel as we go through the portal. There is a slightly blinding light, but I don't flinch. Then we see them. Dean is standing there with another guy who I don't recognize. I think that they don't have the angel blade, but then I see a sparkling piece of metal. The blade. See Dean's face of awe as Castiel's wings come out. Then so do mine. Then Dean runs forward and stabs Cas with a sword. I gasp as first, but then realize that it can't hurt us. Then Castiel starts fighting back. He yells for me to go after Dean. Dean has his back to me, so I jump on his back, and use my momentum to swing us against the wall. I jump off him, and pull his arm back so his right wrist is touching his left shoulder blade. Now that I have him against the wall, i see just how tall he is. He looks about 6'1". Wow, he is a little over foot taller than I am. I'm 16 and at 4'11" weighing 95 pounds. Cas would always make fun of me because of how small I am. Now that I see how tall Dean is, I start to wonder exactly how tall Sam is. I look over to Cas. He is still fighting the bigger man. I call for Cas to trade me people, and in that second I open my mouth, Dean pulls his arm free, and elbows me in the mouth. I curse, and he got me pinned up against the wall. His arm is pressed against me so that my shoulders are pressed against the wall without cutting off my air. I don't scream for Cas because then Dean would bring his arm up to my throat. Then I see Dean grab the angel blade. I scream and Castiel looks over at me. He gasps, and ties the other guy up. Then Dean speaks,

"Take another step, and he gets it."

It doesn't even sound like he spoke, it's more like he growled. He moves his arm, and it bumps my hat, and it falls off. We both gasp as he realizes that I'm not a guy. He raises his hand to feel my hair and I flinch thinking that he might still stab me.

"Hey, I'm not going to kill you. Just tell us what you want."

"We are here to protect you and your brother Sam, Dean. We are not going to hurt you. My name is Castiel, and this is my little sister, (Y/N)." Cas says still not approaching Dean in fear of him stabbing me.

"H-how do you know my name?" He stutters.

"We have been watching you."

"Now that you know we won't kill you, will you please let me go." I ask Dean.

"Oh, um, yeah, sorry." He lets go. I bend down and pick up my hat and put it back on.

"Sooooo, you're NOT going to kill us?" Dean asks again.

"As long as you don't try to kill us." Castiel says.

"Okay, you've got yourself a deal."
