Good episode, but it felt like it was a lot of set up for upcoming conflicts, interactions.
So there's a buried, aging nuke on the island, wonder if this will play into the future? I can only imagine how the time shifts might effect a nuclear device. Those old bombs required a very precise sequence of detonations to start the nuclear chain reaction, especially in hydrogen bombs, so if the explosives are kaput, it should be relatively harmless. Relatively. Anyway, a theory, that woman with the gun on faraday, could that be his mother? He said she looked so much like "her". Who knows?
