When trying to escape the asteroid in the shuttle pod it is stated that they are having trouble with one of the thrusters because an intake manifold is jammed with debris. Thrusters are like rockets, they have contained fuel sources, they do not intake air like a jet, and even if they did, they are in space and there is no air to intake. See more »

T'Pol's Tour De Force
12 August 2007 | by (Vulcan) – See all my reviews

Jolene Blalock finally got the opportunity to show us what she is made of in this action-oriented episode. And she handles her role very admirably.

The episode has a clever opening sequence bound to pull most viewers in immediately. T'Pol is in sick bay screaming and accusing Archer of murder. We then go one day back in time and discover how they got there. The story begins when Enterprise locates The Seleya, one of the Vulcan ships lost in the expanse, and finds that there are life signs aboard despite the very heavy damage the ship has taken on.

The episode is reminiscent of first person shooter video games, and the action does become a bit tedious after a while. But Blalock's 'torn loose' performance is enough to keep it interesting.

A final comment - there is a fairly massive plot hole involving the Vulcans and their medical science, which astute viewers will pick up on immediately. Don't let it bother you.. Enjoy it for what it is - one of the better Enterprise episodes.
