I feel like I could make a really compelling case that Teal'c and Daniel Jackson are closeted, late-blooming gay or bi men who could have fallen in love.  For one, they both have wives they never really seemed to want to spend time or have sex with.  For another, they held together pretty well when events forced them and their wives apart.  Hey guys, I've been there.  You think you have to settle down with a woman because that's what everyone expects of you and you're doing your best, but they never really seem to complete, you, you know?  But Teal'c smells like home and Daniel is adorable when he furrows his brow over something and you should just hold each other to get through this hard time.  And maybe make out a little, just to see.
