I don't think we can conclude that is it.. I think it's something that will linger. Remember, for people in NY, the RFK assassination was huge; but it happened while they were sleeping, at night in California... so the impact wasn't as immediate or in a place where they were awake to think about it right away. I think it also captured how numb everyone was to these events; it was shocking.. but it was just another shock along the road.
I was hoping to see the "as they hear about it" reaction from the younger staffers, especially Peg. I hope they don't just drop it next episode. That would be a huge let down.
