Sarah attempts to find the man who will be responsible for restarting Cyberdine(Cameron informs Sarah in the previous episode that another takes Miles' place as the one who leads Skynet into its ultimate goal in the destruction of the human race)by going to Miles' wife, discovering it was a pupil of his named Andy. John and Cameron(posing as his sister)go to school as Special Agent Ellison visits the crime scene of the freedom fighters. A scientist is visited by the reassembled Terminator needing synthetic skin, giving him the formula to do so. Sarah decides to get a little closer to Andy to see if he has created a computer or technology which could lead to the Skynet disaster where artificial intelligence advances to the point where humans become obsolete..John calls it Singularity. A computer Andy calls TURK 2 could be a sign that Sarah must act(Cameron says Sarah should kill him). In school a teenage girl is the constant victim of a cruel prank which results in her jump from a school building John so desperately wanted to disrupt, with Cameron not allowing such a desire due to possible identification for those out to get him. It is established that agent Ellison isn't in the good graces of fellow FBI special agent Greta Simpson(Catherine Dent)who believes the crime scene involving the freedom fighters is merely a drug related incident connected with Enrique(although Ellison believes otherwise). Adam Godley is the chem scientist who helps the T-1000 only to be repaid in sadistic fashion. Glau has some amusing moments in the girl's restroom with other teenagers who find her offensive and socially inept. There are times in this episode when Dekker's John looks over at Glau with little on(she's a cybernetic being, not human and so needs coaching on proper etiquette around the house, including chores)and must force himself to remember what she really is. John also scolds Cameron for acting weird around other high school kids. The suicide and what led up to it is pretty shocking in how it unfolds. Brendan Hines is the really likable nerd who built the Turk, and he shares surprisingly good chemistry with Headey who must hurt him in order to "save the human race." Another startling revelation from Cameron..in 2005, Sarah was supposed to have died of cancer, yet the time leap two years later changed all that. A doctor's visit proves she's in good health, but I imagine the cancer aspect doesn't end here.
