Well...this and Evolution 1 go down in my absolute favorite, could watch a million times over, episodes. A fun adventure. It felt like old times, though everyone wasn't together the whole time. And, IMHO...any episode that includes Jacob and Bra'tac is worth watching till you go blind. Love those guys!
And, by the by, I really never see any hesitation or irritation in Jack's behavior toward going after Daniel. I think he was worried and more than willing to go after him, but also worried about the threat Sam/Teal'c were going to have to work toward solving.
