"So, you see Cam as kinda like Marcus, with a human brain and mostly mechanical body.

And the memories of the interrogation were not real, but imagined/hallucinatory memories that arose following the trauma of her suffering.

While I'm not gonna embrace this as my new belief, it certainly is not impossible. And it opens up new ideas about where Cam's relationship with John can go to."

"Hi, guys - been off the wiki for ages (v busy) but also because we are starved of ourTSCC!

This matter is one I addressed some time ago, and came up with a theory that many found ro put it politely - outrageous! I happen to believe Cam and Allison are one and the same. Vestiges of Allison remain within the person we know as Cam. How did that come about? I believe that Allison went on an emissary mission for Connor to the "join us" crowd. Her party were perhaps ambushed, and she was mortally wounded, and was later found by the Weaver rebel faction, and "repaired". Not so unbelievable when you consider Stece Austin, when the technology was certainly no where as advanced. Cam's switch ingointo Allison is more than just emulation. This is a serious switch of personality. And the entire interrogation could well be Alison's lasr moments as the perosn she was, imagining what was hapening to her as a terrible "interrogation". The faction probably had to use basic >Skynet programming, as tht might have all that was available. (If we ever get a seasn 3 and Cam returns, odds are she'll be "modified" with the base program removed)

"Writing the nth fanfic I was looking for theories, and I found this page...
First of all, when she says she is different... she is different compared the old T-800 John knew when young!
I think you have to concentrate on what the writer was thinking while writing too.
While watching the episode for the first time I thought he was quoting, saying Cam had imprinted memories and we were seeing cam... that was a bad quote, and we then discover Cam was interrogating Ally, so there was no imprinting... and no quote.
I don't think there is more part of Ally in Cam than some constructed memories needed to infiltrate... There is no personality, soul...
Surely there are not part of brain or body, since Ally was alive when Cam was yet ready.
I think Ally's memories came back cause the damage on the chip, but this happened in a second moment: at the first moment she remembered nothing.
I think what we have seen in s02e04 is the real Cameron: without memories, she was free from thinking "I'm a machine, I can't do"... so she has been herself.
When John naively remembered her what she was she began to forget who she was.
I've another complementary theory, (I think both things happened) but I'll use it in my fanfic, and it's more technical... and doesn't involve soul or ghosts too..."

"Yes, it suggests the memory wipe either did not happen or was incomplete.

Either that or the memory wipe process is imperfect. Like on my computer, when I "delete" a file, it is still on the disk but its name has been removed from the file system table of contents, so it cannot be easily found.

i choose to believe that Cam was captured when she tried to infiltrate Resistance HQ. Then she was given a standard memory wipe and reprogrammed to follow future John's orders. The memory wipe was either imperfect or incomplete so the Allison memories were still there, and they bubbled up somehow during Allison from Palmdale."
