I quite liked seeing the faces of the conspirators, as it reminded people of who all the various players were and added more visual interest to the scene. That shot of Chang mid-transport in particular is great. Showing, not just telling. The Colonel West reveal, I can take or leave. I rather like the idea of a turncoat Klingon actually pulling the trigger, as it adds to the idea that it's humans, Klingons, and Romulans all conspiring together. So the Colonel West reveal was unnecessary, IMO. Absolutely!
