Okay, I'm a big dummy [*SPOILER ALERT*]

And no, the spoiler is not that I'm a big dummy.

I'm confused by the scene near the end of the film where Joey and Zara - the FBI agent whose been trying to track down the film - both show up, together at Skip's shack, looking for Skip and the missing frame of film. So...Zara's in on the espionage and working with the Commies, I guess..?

But if that's the case (and I don't know how else you'd interpret this scene), then why is this little matter of a treasonous FBI agent never resolved or referred to in any way afterwards? You'd think there'd at least be some kind of brief scene toward the end where we get to see Zara getting cuffed and hauled off for his crime. I mean, if you're gonna throw in a traitor agent that late in the game, do it for a reason and actually do something with it.

And what about the other FBI agent who's been posted near Skip's shack to watch it? Surely Zara knows the guy is there, so why would he show up with Joey only to (assumedly) be spotted there with Joey?

Unless I'm completely missing something here (and I don't rule out that possibility), it seems like throwing in the business at the last minute of having Zara be a turncoat is just sort of random and not very well thought-out, sloppy, even.

But I'm willing to be convinced otherwise, or hear other explanations for the scene.
