Watching the Defector, I love the after the opening credits chase of the scout ship and the Romulan cruiser. The ships in HD look great. The close up of the scout drifting over the Enterprise is really nice. I really wish they followed up on this episode in later seasons maybe when they had Spock on Romulus. The shots at the end with the Enterprise turning into the Romulan ships, is excellent. What Enterprise model was used for the shots in this episode, the details on it really stand out in HD. This is one of my favorite season 3 episodes.
