There are only three episodes left this season, and "6:02 AM EST" was primarily an hour that refreshed our memory of pertinent storylines and moved the characters into positions for the big finale. There were some great character moments to savor and a few surprising moments, but overall this episode was only "good" in the sense that it focused on the nitty-gritty of season 3's concerns (the Doomsday Device in particular) and made some welcome adjustments before the real fun begins...
There were some big events in this episode that fans have been awaiting all year for regarding the Doomsday Machine, but in many ways they were handled disappointingly. The use of Walternate's grandchild to cheat the machine was predicted weeks ago, and felt like an undramatic cheat. It remains to be seen if that entire storyline with Fauxlivia falling pregnant only existed because it's almost impossible to get Peter back to the other dimension in a logical way. But there's still lots of potential in the sci-fi soap storyline of Olivia discovering her boyfriend's fathered a child with her inter-dimensional doppelganger, and it was refreshing to see that Fauxlivia has changed her opinion on Walternate and his methodology -- perhaps because she's become a mother and understands the value of life. Maybe it was a mistake to give Fauxlivia a sudden relationship with Lincoln (Seth Gabel) however, as it's neatened the love-triangle into a less prickly square.
If I'm honest, Walter's constant blubbing about his past transgressions and fears that he'll lose his son have started to lose their impact, with Noble expected to deliver another spin on the same basic scene with co-star Jackson. However, having Walter (the epitome of a "man of science") seek some comfort from a nearby chapel, urging God to punish him for his crimes but save their world, was an effecting moment. Beautifully played by Noble, even if the quality of writing didn't quite deliver the knockout emotion that scene was promising. I note that three staff writers are credited on this episode (David Wilcox, Josh Singer, Graham Roland), so it's a shame not one of them could craft dialogue that took full advantage of Walter grappling with his spiritual side.
- Fauxlivia's son is named Henry, after Henry the taxi cab driver who helped during the birth.
- I liked the mention of Walter receiving a sign from God in the white tulip he was mailed during season 2. A moment he evidently sees as a miracle, but which audiences know was the result of a complex time-travel storyline he has no knowledge of (see: "White Tulip")
- Still no sign of an explanation for why Peter (well, his DNA) triggers the Machine, which was built aeons before human civilization began. They do have an explanation, right?
