Oh, ta for the link. *bookmarks for later* Yeah, actually, it's much easier to get my head around it if one or both of the characters is USTing after someone else. (I guess that says a lot about my tendency to wear ship goggles.)

That's maybe one of the reasons there's so little Sam and Jack friendship fic – because so many of the story variables that might be applied to their characters in a Stargate universe are already perceived to be shippy.
