I'm horribly confused

[switch842]

I think someone else may have posted this in their LJ recently, but I'm watching Upgrades on the Monday Night Marathon and I thought I had figured out where Jack and Sam went at the end, but now I have no clue. I thought maybe they went to go do something with the timers - delay them maybe since they couldn't run as fast anymore. But then when Sam gets up to leave, she makes a grab for the naquada pack that Daniel had been carrying that they left behind. So did they just run around in a big circle for the fun of it or something? I confuzzled..........
