A pairing you've rooted for since the beginning?
Of course it's gotta Sam and Jack. I've definitely rooted for these guys since I first started watching SG-1, allllllll those years ago. First active fandom I got into, and am still a part of to this day. That's around 11+ years of shipping these two, and still going haha. Love them - Sam and Jack forever! ♥
(In fact, whilst hunting for the pic above, I came across so many great pretties and funny things on Tumblr about this pairing that I'm finally going to create an account on there myself to join in the madness ;) Yay!)
