Fringe : Season 3 : Episode 20 : “6:02 AM EST”
Walternate updates his master plan.
Tensions start to build up for the finale of season three with Walternate activating his Machine and the Fringe team on Earth-1 scrambling to counter-activate theirs. Seeing as Fringe has been renewed for a fourth season, I somehow doubt that Earth-1 will be destroyed.
This episode is debunked at Polite Dissent and Cordial Deconstruction, and you can read more about it at Fox, IMDb and the A.V. Club.
Random thoughts
Faraday cages have been mentioned before, in season two’s White Tulip, as has quantum entanglement (6B, Entrada).
J. Robert Oppenheimer‘s famous quotation, “Now, I am become Death, the destroyer of worlds” is from the Hindu scripture the Bhagavad Gita.
When examining the granite, Walter uses a piece of equipment that looks like an analogue multimeter, but that emits clicks like a Geiger counter. Presumably he is measuring the potential difference between the terminals (as seen by the needle moving), but then what are the clicks for?
