Well, I believe that such a scene wasn't necessary. I looked down, thought about it.. but, the story, being the archetype of the adventrue, needed to expand at that point rather than stop for reflection. The narrative was picking up momentum, and following ht beats along that path.
I think that's what I hate the most about the prequels, is that Lucas didn't pay enough attention to the how the stories are paced, and how you can build momentum from emotional and narrative landmarks and move forward. He was nearly able to achieve this at the end of ROTS, because the Order 66 really takes the narrative and thrusts it forward.
