This is one of my favorite eps, too. I particularly love the moment when Archer is refusing (rightly, imo) to change course yet again, and T'Pol simply says, "In all the time I have been aboard Enterprise, I have never asked you for anything. I'm asking now." And he just looks at her and orders the course change. That's a beautiful moment, where he puts his whole ship on the line because he trusts
her.
