Trip has to remove a lid on top of the warp reactor, in order to manually shut it down. He replaces the cover and begins to move back the way he came... but an explosion rips through the side wall, knocking him through the air, striking the high walkway on the other side and down. He falls in slow motion, landing on his back... his head hitting the floor below. Silver metallic dust settles on his face.
The Enterprise abruptly comes out of warp, and into a field of red clouds.
T'Pol: (replying to Archer) "Some kind of polaric field, approximately eleven thousand kilometres in diameter. Composition unknown. I'll need more time to complete a detailed scan."
