I thought the parallel turned out to be a really strange one because it turned out that Neil Caplan was an NSA agent who
knew all along who his wife was. Therefore, in the sense of who had the advantage of knowledge, the situation was not the same as the Bristows at all. In fact, Elsa Caplan is more in Jack's position in the sense that she is in the position of having less knowledge of her situation, and also of putting first priority on her family (not to say that Neil Caplan does not also do this). To say that Jack is "more stupid" than Caplan when Caplan
was informed of his wife's affiliation is rather unfair to Jack.
Jack's story about the spy-wife: how much of this is what he believes about his own situation and Irina? That's a good question. He meant to be hard on Elsa because he wanted to push her hard enough to get a true reaction out of her. He probably pushed her a little harder than he meant to. But choosing the harshest of terms is part of the game. Does he also believe what he said? Maybe. It's hard to tell where the game leaves off and the truth begins. Where does the interrogator leave off and the injured spouse begin? I don't think we've seen a fraction of the injured spouse yet. Jack hides that man too assiduously. But we saw a glimpse of him.
As I've said, I hardly think that Jack could imagine that Elsa or any woman could "be Irina Derevko." Irina is too . . . Irina--too unique. Is anyone else so poised, subtle, charming, manipulative, dangerous?
Was Sydney "an accident"--as in, did Irina's birth control fail? Perhaps that is what Jack believes.
He probably wanted children. As to Irina, who knows? It's possible her birth control did fail and she decided to keep her child, either because she felt, as Jack suggests, that a child would redeem the evil that she does for the sake of her job, or because she loved Jack and wanted something good to come out of the marriage, something that was theirs, lasting, and symbolic of the love that existed between them. Or maybe she decided to "let" the birth control "fail" (so she told her handler) for the same reasons. Even if Sydney is "an accident," or, worse yet, "part of her cover" (as Sydney suggested last season), it seems clear that Irina has some love for her daughter, for she wants to preserve her life and seems anxious to reunite with her in time ("the truth takes time"), but it also seems possible that Irina would sacrifice Sydney in service of her quest for Rambaldi's truth.
Dang, this turned out to be long!
