My view of SG-1 is that they all love each other deeply , but that they're not *in* love with each other. I see them more as siblings.

When I first saw episode that hinted at Sam and Jack having romantic feelings for each other I was dispointed. Can't a man and a woman just be friends. ? Sheesh.

I've finaly rationalized it as the two of them loving each other and noticing that the other is atractive, but the military protocoles they try to maintain preventing them from analizing the situation long enough to realize that they're not *in* love.
