The Enterprise meets up with a Vulcan ship and Archer is NOT thrilled. After all, many of the Vulcans he has met have been jerks--haughty know-it-alls who simply cannot be trusted. So he's surprised and quite happy to learn that these are not like normal Vulcans--these folks embrace emotions and seem much more normal. T'Pol isn't thrilled by the meeting, as she's been raised to embrace logic and eschew emotion just like almost all the others of her species. What's next?
This is a decent enough episode. However, near the end of the show, one of the Vulcans hurts T'Pol and I loved watching Archer's reaction. He was very protective of her and it was actually a bit touching seeing him stand up for her. Well worth seeing.
By the way, the notion of feeling and emoting Vulcans was also explored (very poorly) in the film "Star Trek V"--a film which is probably the most hated of the Trek films.
