That was the point of the episode. It was when they started mellowing out. The irony is that in this case Archer begged them to interfere, while Kirk wanted just the opposite. A smart episode, I would say. (Except for the Hoshi breaks out of jail scene, that was silly).
Yes, for Enterprise this was a really smart episode and the jail break was silly! I also noticed that Archer had a Buzz Lightyear kind of vibe about him this season, but all of that being said season 4 is the best of the show, even with the stinkers!
