Needed Explanations

[fangirljen]

With the release of spoiler pics for "200", I once again find myself asking a question I was asking months ago: Sam and Jack, how exactly does it work as a relationship?  It's a popular pairing in SG-1 fandom, but it's beyond me as to why it is so loved.  I see sexual tension, but it's hardly been confronted, and has never been resolved.  So for those of you who ship this pairing, why does it work for you?  Also, how deeply are they involved in their relationship?  What I'm looking for, really, is a well-researched argument that could convince me to like this pairing.  It feels forced to me and Jack seems cold to it.  If you can point me in the direction of any articles on the ship, I'd greatly appreciate it.
