I like this. I've always imagined Sam and Daniel as being totally in love but completely blind to it until something or someone smacks them in the face with it. I think the way you describe it in the end of this is perfect!
Oh, and Jack's a jerk. :)
I found this interesting at first, but gave up about halfway through because the formatting of characters' thoughts has actually removed their thoughts. You might want to re-upload this. I'm sure the story would make more sense and be even more interesting with those thouse visible.
