First of all, welcome to the SCS! Discussion of topics can be a bit slow at times but its great to see new members.
So, in Terminator 5, we see that, Robert Patrick, the T-1000 unit, is a Stem-Cell Research Scientist... ok, so we see that..
Source?
I hadn't heard any details on T5, so thats a new one.
The rest of the post is a bit on the fragmented side, makes it tough to reply to without repeating some of it.
The human copy / template SkyNet used to make the T800
- He probably was a resistance fighter like Alison, and at some point captured. His muscular body size was a good fit in proportion to a T800, so SkyNet probably chose his appearance for the Series 800, model 101.
Why did John Send back an identical T800 that was sent after his mom?
I'm guessing at the time SkyNet didn't have much variety in their T800 line for appearances. Like a car manufacturer - create one template and use that for the production line. Perhaps later SkyNet realized one appearance would / has become recognizable and too obvious? Once a 101 model was recognized by the Resistance, its not possible for further identical 101 units to infiltrate the same place.
In one of the older comics, they do explore the choice for UncleBob to be sent back. Whether or not how Cannon it is, its one possible explanation. John Connor had led a team to break in to one of SkyNet's facilities, one with a TimeDisplacement machine. Some of the standby T800's activate, and the team manages to destroy most of them and disable / deactivate one intact. They dig out the cpu, plug it into the portable computer they brought. reprogram him, activate him, make sure he's accepted the reprogramming and send him back to protect John. Only weak spot there is having cut the skin tissue to get to the cpu cap, if there was any metal exposed it might not have worked.
Remember, Arnold's unit was model 101. There might've been more variants later on with different numeric designations. Model 101 might have at the time been the most common and abundant unit style.
Additionally, Kyle Reese was only one of several hundred humans captured and put into the concentration camps.
SkyNet had some large concentration camps for keeping human prisoners. So unless theres a specific attribute SkyNet was looking for, it probably just picked prisoners at random to copy for appearances.
Also, its likely that once SkyNet chooses a person's appearance to replicate, it likely destroys the original human. In TSCC Alison was one of those prisoners, escaped only to take her own life so she couldn't be interogated further.
Never played it.
Agreed. And it was a great cliffhanger for a Season 3.
