No, no, no, you are both wrong. "The Sarah Connor Chronicles" is a SEQUEL to T3.No. TSCC, as has been already stated, completely ignores T3. The majority of the events of T3 take place in 2004, while, in TSCC, we have Judgment Day being pushed back to 2011 after the events of T2, and the majority of the events of the series taking place in the present day (2007 as of the start of the series).I actually thought that TSCC was created as a vehicle to (retroactively) make T3 possible in the first place?
Here's the chronology: In T1, John Connor had sent his father back to 1984 to meet his mother, thus causing his own birth. And the Terminator went back in time, leaving parts behind that Dyson would find, thus causing his own creation. So that is two predestination paradoxes.
In T2, more time traveling cyborgs come back in time, because the predestination paradox created in the first movie caused absolutely nothing to change. So this time, instead of fulfilling their own destiny, the characters actively work to change their future. The Terminator knows that in his future, Skynet was created by Dyson and Cyberdyne, so they destroy Dyson's lab, and all remaining Terminator parts.
Sarah Connor would later die of cancer.
In T3, the U.S. Air Force is working on its own version of Skynet, independent of the events of T2, which allows more Terminators from the future to come back to 2004, help John Connor meet Kate Brewster again, and the TX uses the Air Force computers to help create Skynet, so like T1, T3 is its own predestination paradox.
After the events of T3 and the nuclear war, Connor becomes the resistance leader he is destined to be in all timelines, and sends Reese back to 1984, the T-800 back to 1997, and the famale Terminator "Cameron" back to 1999, where she meets teen-age John Connor at the beginning of "The Sarah Connor Chronicles." John Connor is then killed by a T-800, and Kate Brewster reprograms that T-800 and sends it back to 2004, where it helps John Connor and Kate Brewster survive Judgment Day.
But meanwhile in 1999, the female Terminator "Cameron," who was sent back by John Connor in the T3 timeline before he was killed, assembles parts for a time machine, also sent back by Connor over many decades, and uses the time machine to transport John and Sarah Connor into the year 2007.
By doing so, she creates a new timeline where John and Sarah Connor are eight years younger than they would have been, and Sarah Connor lives past the date when she originally died of cancer, as mentioned in the series. It is from this new timeline that John Connor continues to live, and will one day send Derek Reese back in time to 2007, where he will meet John and Sarah Connor and "Cameron."
As they continue to meet new Terminators who keep coming back in time to change the past, they also continue to change the future that Reese and "Cameron" remember (they remember each other, even though Reese and "Cameron" cannot be from the same future, since "Cameron" created a different future from her own by traveling back and then forward in time with the Connors).
Derek Reese meets his former girlfriend, Jesse, who is from yet another future and came back after Derek because she thinks "Cameron" is a bad influence on John Connor. Jesse and Derek remember different events from the future, but they rember each other, so their futures must have been similar, and they also remember "Cameron," who is from yet another future.
So basically, every time anyone travels back from the future, it is a slightly different future, where the time traveler remembers slightly different events than the previous time traveler.
"Cameron" comes from the T3 future, where she remembers Sarah Connor dying of cancer. Derek Reese comes from the alternate future resulting from "Cameron" taking the Connors into the year 2007. And Jesse comes from yet another future resulting from the changes Derek Reese has made since arriving in 2007.
Within the logic of the "Terminator" series, "The Sarah Connor Chronicles" is a sequel to T3, since the initial time travelers in the first episode came back from the future of that movie.
I have no idea what the plot of T4 will be, but if Kate Brewster is a character and John Connor is still alive, then it must be a PREQUEL to T3, before John died and Kate sent the T-800 back to 2004.
Therefore, the logical story order of the "Terminator" series would be T1, T2, T4, T3, then TSCC, because the time travelers in each one remember the events from the previous one.
