What I gathered from this episode is that from the post-credit sequence untill we go bavk to the tent, it's all in Daniel's head. A sort of odd "mind perspective" thing where from a certain perspective in your own mind a long time can pass, whereas in realtime only seconds do. Dreams are like this. Sometimes a dream can last 30 seconds and the events can take hours, sometimes a dream can last minutes and the events last seconds. Thus the title:" Forever in a Day. Great concept, this ep. The delivery is good, but not great though. And Teal'c prolly picked up a staff weapon becuase they are better battle weapons. One shot, one kill as a pose to having to hit your target twice.
