Dean looked at the note Cas had left behind. Of all the time for Cas to disappear. Dammit Cas during a case. He opened the letter.

Dean

I got called away. I have come to understand you are suppose to explain why you leave if you go while everyone is asleep. I will be back soon.

Castiel

No PS or a letter for Sam. Dean smiled. He pulled out a piece of paper and wrote a return letter. He left it in the place his letter had been. Sam saw Dean leave the letter. Dean never really did things like that for anyone. Cas wasn't anyone to Dean though. Sam knew it, hell even Bobby knew it. The only two ignoring the elephant in the room were Cas and Dean. But Dean wasn't going to talk about, so Sam wasn't going to bring it up. Besides they had a monster to hunt.

Cas came back a few moments after the Winchesters left. He saw paper exactly where he had left his letter to Dean. Cas's heart dropped. Maybe Dean hadn't read his letter or hadn't cared where Cas went. He walked closer to the paper to pick it up and throw it away. That was when he saw it was not his letter to Dean but a letter to him from Dean. He eagerly picked up the paper and read it. He absorbed all the words.

Cas,

You never leave during a hunt. I don't care why. YOU NEVER LEAVE DURING A HUNT. We stick together.

Love you to,

Dean

Cas stared at the words. To? What did that mean? He knew what love you meant. It was what he had for Dean whenever he make a joke that wasn't funny. Or when Dean would kill something and there was blood everywhere and Dean would just take care of everyone else in the room but himself. Love you was the emtion. The words to at the end confused him. Love you to. Love you to the end of time. Love you to New York. Love you to the world? Love you to Dean? His human companion was confusing.

Cas sat there wondering what the to meant until Dean came back with Sam. "I am confused." he said when the door opened.

"I am confused as to why you would leave while helping us with a hunt." said Dean

"I told you I had to. I am confused about the to." said Cas

"The what?" asked Sam

"The to at the end of love you." said Cas

The color drained from Dean's face. "That is the response when you tell them I love you." said Sam

Cas still look confused so Sam added "Like you would say I love you and the person who you said it to would say I love you to"

"But I never told your brother I loved him." said Cas confused

Dean went as white as a sheet. "You don't always say it with words." mumbled Dean

"But how would any of my actions say that?" asked Cas

"You just left me a note." said Dean trying to defend himself

Silence filled the air. "Dean never says I love you first." said Sam

"But he just did." said Cas

Dean didn't have a voice to say anything, so Sam said it for him. "He implied you said it first and thus he said it second."

Cas looked confused and Dean was growing whiter. Sam decided to leave them alone. "So do you feel that way also?" asked Dean barely wanting to know the answer

"Dean, that is the emotion I have ever felt for you outside of occasionally disappointment." said Cas

"Oh that is good." said Dean now a bright shade of red

"Do we ever do the stuff you do with women?" asked Cas

"Is Jimmy still there?" asked Dean

"He always will be." said Cas

"Not unless he wants to." said Dean

Silence again filled the room. "I love you to." said Cas

"You said it first so you can't say to." said Dean

"You said it first and said to." said Cas

"No, I wrote it first. You actually said it first. So I love you to." said Dean

Cas didn't understand why the to was important or why who said it first was important. But he smiled, anyway you looked at it Dean and Cas were in love. That was enough for both of them.

Well there you go. Much love.
