^They worked it into the narrative frame, but it wasn't integral. There are plenty of examples of films that the protagonist narrates where we don't see him literally telling the story to another character at any point in the film (American Beauty, Spider-Man).
Even so, it revealed something new and surprising about the film we'd just seen. It added something and was satisfying as a result. This scene didn't reveal anything new about the story we'd just seen or set up anything about future episodes. The only thing it revealed is "Sam Jackson is willing to do cameos." I just think that if you're going to get Nick Fury in the show, it should be for something more substantive than this.
Yes, we all get that it's a conditioned response of some kind. We got that from the moment he first said it.
Then I don't understand why you're arguing with me when that was my exact and entire point. And no, not everyone got that; when I suggested that last week, someone said they thought it was just a running gag (though that may have been on another BBS). My point -- on which you and I are in complete agreement -- is that the line's repetition here pretty much rules out the idea that it's just a meaningless gag.
However, there seemed to be something more in the way he said the afterlife line. There was a bit of sadness in the delivery. He may know more about what happened to him than the others think.
I think anyone who came that close to dying would have some strong and painful emotions about it in retrospect, regardless of the circumstances of their recovery.
So Skye fills in the companion's role in Doctor Who, acting as the audience's guide into the world of these secretive agents and serves as exposition, explain things to the audience.
That's a pretty widespread trope, an audience surrogate who's new to an organization so the viewers can learn along with them. Most screen adaptations of
X-Men have started out from the perspective of a new recruit getting things explained to them -- Kitty Pryde in the '80s pilot, Jubilee in the '90s series, Wolverine and Rogue in the movies, Nightcrawler in
X-Men Evolution.
Which kinda means that from a writer's perspective, she would never betray Shield... or at least this team of Shield agents.
I'm not sure why that would be the case. Once the need for the initial expository-audience-surrogate role has passed, they'd have to find something different to do with her.
I'm not sure if I'm reading too much into this but her hesitation at replying "I'm in." suggests she's decided to switch teams and the message serves to temporarily protect her new found Shield friends from whoever her master is.
The vibe I got is that she has divided loyalties... she's coming to identify with the new team, but she still has a loyalty to the Rising Tide and isn't ready to abandon that completely. Changing allegiance or views is rarely so simple as flipping a switch. And we saw here that she still believes strongly in the principles that Rising Tide represents. After all, it's not as if she's changed her beliefs. She's just come to see that SHIELD's methods aren't necessarily as much in conflict with her beliefs as she thought.
The message does imply that she intended to be recruited all along, that she set herself up to be brought in as a mole for RT, and that she's now succeeded in that goal. I have a bit of trouble believing that, though, since Coulson's attempt to recruit her was rather unconventional and difficult to predict.
And as I haven't seen anybody make the reference, I'll state what I'd been assuming was obvious about Ward...he's James Bond. Completely self-sufficient, action-oriented field agent who considers his teammates a liability to his operating style.
There are two reasons I can think of why Grant Ward is very much not James Bond:
1) He hasn't already slept with Skye and Simmons.
2) He tried to save the enemy soldier from being sucked out of the plane -- and he said under truth serum last week that he didn't feel good about the times he'd had to kill. Bond would've gladly pushed the soldier out of the plane and made a joke about it.
