Three days after their jump to 2007, John is completely bored at home while Sarah and Cameron are seeking new identities. They visit the forger Enrique, an old acquaintance of Sarah, but the man tells that he is retired and indicates his nephew Carlos that demands twenty thousand dollars for the business. Meanwhile John visits Charley Dixon in spite of Sarah's recommendation to stay at home. Later the trio gets the necessary money for the IDs in the safe of a group sent from John from the future to help Sarah but eliminated by a terminator. Cameron explains the fate of Sarah if they have stayed in her timeline. When Sarah and Cameron overhear a conversation of Carlos with another gangster, they suspect that Enrique is a snitcher, and Cameron takes a decision against Sarah's will.
The second episode is actually a sequel of the "Pilot", with Sarah, John and Cameron settle themselves down in 2007 and getting new identities. The travel of the Cromartie's skull to the future apparently contradicts the explanation of time travel of the first episode; there are people studying the lines and trying to explain it, but at least for an average viewer like me it is not clear and seems to be a plot hole indeed. The relationship and attitudes of Sarah with Cameron are ungrateful and unjustifiable. My vote is six.
Title (Brazil): "Gnothi Seauton"
