Well, ideally Charley ought to join the team as their resident medical specialist, given how often they get messed up.
Sure, he could teach him first aid - that's not likely to improve his strategic abilities any.
I have now modified my thinking based on this past Monday's episode. What triggered my new thinking is the fact that Weaver now knows - if she didn't before - that there were two Terminators involved in the Serrano Point incident, and that they were fighting. Ellison did not understand the significance of this - but I believe Weaver does.
I now believe Josh is going to kill off Cameron.
The reason I believe that is Tom's statement that the reason the "Big Death" is so shocking is not so much WHO dies, but that the death directly leads to the creation of Skynet. And there's only one person on the show who can do that.
Follow me here:
I believe Catherine Weaver is looking for Cameron. She intends to take Cameron's chip and marry it to "The Turk" somehow to create Skynet.
Because Cameron is the first Terminator to "cross against the light". She is the first Terminator to be able to not only be "self-aware" (most Terminators actually are) and not only to have a sense of self-preservation (beyond the usual Terminator sense necessary to complete their missions) but who is actually to some degree self-programming. Whether this is because of John's reprogramming over the Skynet programming, or an artifact of Skynet's attempting to program the perfect infiltrator to get Connor (which would be ironic since Skynet's self-awareness is presumed in the mythology to have been an "accident"), or an accident of some sort, or a glitch (Skynet should never have used Windows Vista as the basis for Terminator programming! ;D ;D), Cameron is probably the first and/or only Terminator of her kind.
Weaver knows about Cameron - because she knows the back story of the Connors, she knows the Ellison case file (just like Sarkissian's thug did - apparently everybody has access to the FBI database! Good work, FBI!
), and most importantly she knows the story of the bank blowup - which included a bank surveillance video still of the Connors - and Cameron.
And Weaver would likely know who Cameron was - because Cameron was Skynet's big attempt to get next to John Connor - which failed.
Skynet also likely knows that Cameron "went rogue" not only from Skynet but from John Connor's reprogramming in the future, and came back on her own initiative to the present. Skynet would have either provided this information to Weaver or Weaver would have deduced it on her own based on any knowledge of future Cameron she had and the presence of Cameron in the present.
Somebody asked why Weaver can't just turn "The Turk" into Skynet. The reason is that Skynet can't afford to give its specifications to any Terminator for precisely the threat that one of them might go rogue and try to destroy Skynet - or even try to become a version of Skynet. Or that the Terminator would be captured in the future or the past and Skynet's specs would enable the Resistance to destroy Skynet.
So Weaver was sent back to find a computer program - any computer program - that COULD be the "egg" for Skynet - and the one Terminator whose CPU could be used as the "seed" - as it were.
So I believe Josh is going to allow Cameron to be captured by Weaver - through Ellison, who will end up "doing the Devil's work" regardless of his intentions - and Cameron's chip will become the basis of the new Skynet.
Now one question which might be raised is: does Cameron, or any Terminator, have any means of "backing up" their CPU as some sort of "image file" - like you do to a PC when you make a bit-by-bit, sector-by-sector copy of a hard drive for backup purposes (as opposed to a file backup which generally does not back up the operating system and other system files). If she could do that, then if she had a replacement chip - such as Vic's - she could recover herself by having John insert the replacement chip, then restoring the "image file" over Vic's programming. Wallah! Cameron is back in action!
That would allow Josh to have Cameron "die" and cause Skynet to be created - while still allowing him to say, "She's still under contract, nyah, nyah!"
Remember, Cameron kept Vic's chip for a reason unrelated to the information it contained. And I suspect one possible reason could be that she intended to use that chip for precisely that purpose. OR another possibility is that she intended to somehow marry that chip to hers to increase her processing ability. That would explain her evident interest in John's statement about "The Singularity" back in season one. She may possibly intend to seduce John and get him to hook up another chip to her - sort of like the Intel and AMD dual-core machines we have now (that's an analogy, not an attempt to say Terminator CPU's are anything like that - they probably already are heavily multi-core or multi-processor or massively parallel in some way.)
Also, I think the time line for events goes something like this:
1) Derek and his squad are captured by Skynet and taken to an interrogation house.
2) Derek and Andy Good (under the guise of "Wisher") are interrogated by Cameron in the basement room. There she learns both that Andy Good made a machine that became Skynet - and also she learns about Allison Young. At this point Cameron does not look like Allison.
3) While Derek languishes for some time in the interrogation house, Cameron captures Allison Young and interrogates and eventually kills her. Note that she probably does not extract any information about "The Wizard of Oz" from Allison, because unless Allison literally spilled her guts about absolutely everything concerning John Connor, it's unlikely Cameron would have got that information. There's no indication that happened.
4) After killing Allison, Cameron makes her move to infiltrate the Connor camp - and is caught and reprogrammed.
5) Cameron for some reason becomes John Connor's most trusted associate, and is given access to the time chamber, and allowed to carry weapons in the HQ bunker, and most crucially, is the one "person" John Connor talks to - possibly because he does not trust or relates to his soldiers. In this latter capacity, she learns John's deepest secrets, including everything about his past, where he was at any given time, etc. Perhaps she also hacked the Resistance computers to gain more information.
6) At some point, Derek and his squad are released. Upon his return to Connor's HQ, Derek sees Cameron - and knowing Allison Young, immediately recognizes that Cameron is not Allison and perhaps remembers her from the interrogation house, thus triggering his immediate identification of her as "metal". He is shocked to find Cameron is more trusted than he is, especially as he probably knows whatever connection Allison had with Connor, and knows that Cameron's appearance means she killed Allison. More than enough to increase his fear and hatred of Cameron.
7) At some point, Cameron becomes not only self-aware with an advanced sense of self-preservation, she reasons that she can only survive in the past - and a past in which the future entails neither Judgment Day or Skynet.
8) Cameron bolts through the time machine which she has access to and knows how to operate.
9) Cameron arrives in the past at some point, probably 63 days before she meets the Connors, although we can't be sure of that. It's also interesting that the bank time machine can go FORWARD into the future - until now the presumption has been that you can only go backward! Cameron tells the Connors the machine was built "so that we would always have a way back home". Home? The disaster that is the future? Something wrong with that statement. And what happened to the engineer who allegedly built the plasma rifle and the time machine into the vault way back in 1963. Was any of that story true? Or did Cameron go back to 1963, build the time machine herself, then move forward to the late '90's to track the Connors. Not knowing from John Connor exactly where they were at the time, but knowing enough - like Cromartie - where to begin.
10) Meanwhile, Skynet, learning somehow, possibly from capture Resistance officers, that a Terminator has "gone bad" in the Resistance view and gone back in time, Skynet hatches the plot to insure its creation. Cameron having interrogated Andy Good, or relying on its own past knowledge of Andy, Skynet resolves to use "The Turk" and the rogue Terminator Cameron as yet another means to insure its own creation.
11) Skynet sends back Weaver with a triple mission: 1) Find "The Turk"; 2) find Cameron; 3) kill the Connors.
12) Future John, aware that Cameron has gone back in time, sends Derek and his squad back to hook up with the Connors. But neither future John nor Derek know Cameron has already done so. Hence, Derek's surprise when he first sees her in the Federal transport van. He accepts Sarah's "she's on our side" for the minute, but during the fight with Vic urges Sarah and John to "leave her". Subsequently during his wounding, he urges the Connors not to believe anything she says - possibly because he knows she is a "rogue", not only to Skynet but also to future John.
Cameron, concerned that Derek knows and would reveal her involvement in the interrogation house, her killing of Allison (perhaps), and worse, that she is a rogue Terminator, attempts to kill Derek during his recovery by smothering him with a pillow as he is unconscious, failing when Sarah walks into the room.
The only part I don't get is why Derek hasn't revealed - or does not know (and why future John wouldn't tell him) - that Cameron is a "rogue Terminator" not under anyone's control.
Possibly John never told Derek about Cameron going rogue for his own reasons. Possibly Derek assumes Cameron actually is operating under future John's orders. He would see that it appears to be the reality - even if he fears that she will "go bad" at some future point.. Or perhaps she knows something about him that forces him to keep silent.
Remember - ALL the characters have repeatedly lied to each other and kept secrets from each other almost from the first episode.
Meanwhile, Cameron pursues her own agenda carefully. She secures Vic's chip as a backup. She slowly seduces John into an emotional attachment to her - and possibly intends to eventually even have a sexual relationship. We don't know what might have happened had not Sarah walked into John's bedroom smelling nail polish in "Vic's Chip". How much farther would Cameron have taken her "just making conversation?"
We've seen from the bar scene that she could have taken that WAY farther. As I've mentioned, if she ran that bar scene persona down on John, he'd be a puddle of sperm and her slave for life! ;D ;D
At least she could have had she not lost it during episode one and angered John by playing on his emotional attachment with the bogus "I love you" bit. Now she's back to square one with John, further complicated by her chip glitches which are making John paranoid about her.
So here we are: Cameron is glitched which might render her less effective in dealing with both the Connors, Derek, and Weaver. Weaver is searching for her, and Ellison will lead her right to both Cameron and the Connors. And we know from Richard T. Jones himself that he meets John Connor - with Cameron. And he gets the worst of it from Cameron, apparently.
The end of this? Weaver kills Cameron - and possibly Ellison - and marries Cameron's chip to "The Turk", creating the nascent Skynet.
And unless somebody backed up Cameron, so John can "restore" her - at that point, the show might as well pack up and go home - because a hell of a lot of fans of Summer Glau are going to desert the show.
Josh - Summer Glau is FIFTY PERCENT of that show! FIFTY PERCENT! Lena is 25%, Tom is 25%. Summer is the rest of the show. The others, even Brian, aren't a factor. Screw up with Summer and Fox might as well kill the show. Trust me!
