This is what I've been hoping they'd reveal, but at the same time I kind of dare not hope we'd hear it because I can't imagine this version of Sam and Dean being open enough for Sam to admit it to Dean (especially since it sounds like they'll soon both be climbing on their high horses and working behind each others' backs rather than communicating like adults), and it's not like Sam has anyone else he can talk to about non-plotty stuff like that. (And even if it was written, it'd probably hit the cutting room floor for being too ~gay or for being too Sam'n'Dean or whatever reason they have for cutting all the scenes we keep hearing about.)
