Chapter 30-Short Term Memory part 2

[Red Shirt]

1st part of chapter 30? Maybe 3rd part of the last chapter, I don't remember exactly but he said something along the lines of "we lost communication with the East, then it hit us." something like that. Can someone help me cite my sources?

Chapter 29 2/3, pretty much the entire first half of the episode is Kimmet's briefing.

At about 4:58, "We lost contact with everyone on the East Coast about a week after the west was hit."
