The point is that HRG from the original timeline trusts him, and doesn't realize that he shouldn't. Hence his quick infodump as soon as he saw nuQuentin.
Yes, exactly. If Quentin had been a mole all along, his entire purpose would've been to manipulate Noah into trusting him so that he would reveal the secret. Again, if Quentin hadn't pushed Noah, then Noah would never have investigated and never would've compromised Tommy and Malina's safety. He would've just kept right on working at the used car dealership. Quentin's actions
before the time travel are thus directly responsible for exposing the kids to Erica, which is exactly what mole-Quentin wanted to achieve. And it's hard to believe that's a coincidence.
I'm curious, did you watch the webisodes that set up the situation with Quentin and his sister? (I'd have to go back and rewatch myself, but IIRC, they directly contradict the idea that he was a mole in the original timeline. But I could certainly see how Quentin might seem more suspicious to somebody who hadn't watched them.)
I hadn't seen them before, but I just did. The first four episodes happen before this week's episode, so they aren't relevant to the debate. And the fifth one picks up three months later. So there's no direct chronological overlap to create a contradiction. As for Quentin's actions in the last two parts, they certainly
look like he's sincerely trying to find Phoebe and bring down Renautas, but that's what we would've been supposed to think even if he had been secretly a mole all along. And given the conceit that the webisodes are found footage recorded by Quentin -- to show to Hero-Truther, in the case of episode 5 -- I don't think we can rule out the possibility that the entire thing is a performance for the cameras, part of a long con on Quentin's part to manipulate Hero-Truther (Micah) into helping him track down Noah's new identity, in the same way that he then manipulated Noah into trusting him. After all, there is a three-month gap between episodes -- plenty of time for Erica to groom Quentin for his role. And why would Quentin wear his pen camera
to his meeting with Hero-Truther... if he wasn't working with Renautas to expose and capture Hero-Truther?
And yes, it looked like Harris was going to shoot Quentin, but he paused to monologue first, giving an Evo time to stop him. That could've been part of maintaining Quentin's cover.
Of course, the webisodes are also consistent with your theory that he wasn't a mole to begin with. But I don't believe they rule out mine.
(Anyway, that was an incredibly self-conscious and forced use of the found-footage conceit. Found-footage is always forced, but there were just so many different times where the characters called attention to the fact that they were on camera.
(But I find it amusing that Harris's first and middle initials are "M.F.")
