Yeah, Pip has probably been in on this one from the start. At least now we have the whole Trio involved. I still think that Squirrel and possible Denizen involvement lies in the near future.
Here's an off-the-wall prediction:
There are no infiltrators. It's just a weird distortion affect that JC's 3D Specs have with certain HD channels on the right kind of TV set. This is nothing but a huge piece of industrial espionage that Cameron is carrying out on behalf of the companies making 3D Cinema technologies: Fooling idiots who have seen too many of his films into thinking the Aliens have arrived and destroying the cheaper and higher-quality competition on the grounds that it is 'protecting humanity'.
Naturally, there would need to be a degree of deniability. I have a feeling that, once the deed is done, the website will just be the corporate website of a 3D Specs manufacturer. The wild stories of Cameron's patsies will be considered either shallow lies in an attempt to justify their crimes of the gibberish of the insane. Either way, no-one would even
think to question a respected, multi-millionaire film director about the crimes of a few hooligans and lunatics!
In so many ways, it's very nearly the perfect crime!
