I think a lot of people took the idea of Dean crawling into Sam's crib after Mary died as law. But there aren't a lot of little boys who are going to continue that behavior past a certain age, and in the Christmas episode we see what I think of as typical boy behavior -- grudging fondness, a lot of teasing, but no real hugging or cuddling.
I can buy that they had to share a double bed in a motel room once in a while, but I highly doubt they were snuggling when Dean was past the age of eight or so, when a four-year-old Sam might have demanded it, or weaseled it out of him, or simply cuddled close in his sleep (which four-year-olds do, complete with elbows in the ear and knees to the stomach).
I might stretch it to Dean being 11 or so, but I don't think even his lack of familial boundaries would encourage it past there, and I'm fairly sure Sam's came up strong and early.
I was describing the fic (as much as I read) to my sister and she was all "So?" "Okay?" "What!?" "Come on!" as I stepped her through it.
And she's touchy feely as shit.
I can see the boys sharing beds, like you say, Amy, in restricted living conditions which probably came up a lot. But that's not skin on skin contact.
Seen the S6 cast and crew picture? I can't believe they finished filming without an official word about S7. If we don't get one, it's going to feel all the more abrupt.
I wonder whose face is on the yellow shirts in the right back.
If the final shot of Season 6 is Sam & Dean disintegrating into a pile of jujubes, I am going to fall out laughing.
Does that mean we get a follow up with canon mpreg?
I'm not sure the world is ready to see a third character carrying Sam and Dean's love child, if we continue the parallel...
Oh, I think we're just about ready for Castiel to hatch that egg. Just about ready.
