Sam and Dean in “Unfinished Business”

Sam

Dean... When are we going to talk about it?

Dean

Talk about what?

Sam

About the fact that Dad's not here.

Dean

Oh, uh, let's see, never.

Sam

I'm being serious, man.

Dean

So am I, Sam. Look, he sent us here. He obviously wants us here. We'll just have to pick up the search later.

Sam

It doesn't matter what he wants.

Dean

See, that attitude right there, that is why I always got the extra cookie.

Sam

Dad could be in trouble. We should be looking for him. We deserve some answers, Dean. I mean, this is our family we're talking about!

Dean

I understand that, Sam. But he's given us an order.

Sam

So what? We've always got to follow dad's orders?

Dean

Of course we do.
