Personally I was half expecting Boulder's communications to be down due to natural causes, but to then be attacked shortly afterwards. I guess we can just assume that Griggs was too strong for the initial team that found him.

Michael is definitely piecing things together, there will definitely be a Michael/Kimmet conflict, and the nukes may not be detonated but will come into play. I do hope everyone in Boulder survives, but I could see Pegs dying just as she's about to be saved by Michael or while performing some heroic act.

Glad to see the return of King Datu the Resourceful!
