In “Homeland,” Showtime’s excellent Emmy-winning drama starring Claire Danes, a G.I. named Nick Brody imprisoned for years returns to the states a hero, and, secretly, a converted Muslim and terrorist. By Season Two, which premiered last night, Brody has risen to be a member of Congress, where he is working from the inside to benefit the interests of his captors. He has kept his conversion to Islam secret from everyone but his teenage daughter Dana, who accidentally caught him praying to Mecca in the basement in the first season.

Now Brody’s name is being floated as a possible running mate for the current Vice President, who is a presumptive presidential nominee. The Veep tells Congressman Brody that if there are skeletons in his closet that his researchers wouldn’t have found—I’m pretty sure being a secret terrorist would qualify—Brody needs to air them. Brody says there aren’t any. We know better.

Meanwhile, at Sidwell Friends, the tony Quaker private school in D.C. that all the pols send their kids to, Dana is fuming because she has to listen to the  Vice-President’s obnoxious son  go on about how “Muslims aren’t like us” and “don’t respect human life.” Dana, having been admonished for insulting him, blurts out, “Well, my father’s a Muslim!” in class.  Dana’s subsequent position is that she was joking to make a point. At home, however, her outburst causes a domestic crisis, as her mother feels that Brody has been lying to her, which he has.

I’ll leave Rep. Brody out of this ethical dilemma, as he is suffering from an Islamic strain of the Stockholm Syndrome, but what about the family? From their perspective, which is that they don’t suspect for a second that Brody is a traitor, what is their ethical obligation should he announce that the Vice President is going to choose him as a running mate, and that he expects them to keep his secret?

His argument, of course, is that his religion shouldn’t and doesn’t matter. It is true that the “public would want to know,” and also that the public would probably not feel very comfy electing a Muslim these days to be a heartbeat away  from the Presidency, fair or not. The family knows he is a good man (they think) and like the idea of being Second Family; there is no reason to sink his career and their aspirations to celebrity by allowing irrational bigotry to take hold. Is there?

That’s not the whole truth, however. Brody has lied to the Vice President and to his constituents, and they do have a right to know that. In my view, both wife and daughter have an ethical duty as citizens to tell husband and father that if he accepts the nomination, they will be forced to expose him. They should also tell him that he needs to resign from Congress, or, if he’s willing, tell the public about his deception and ask for their forgiveness. I think, in short, that this is a John Edwards situation.

Is that what you would do, in their place?

And my favorite hypothetical of them all, that I refuse to believe wasn’t lurking in the minds of the writers:

Michelle discovers Barack praying to Mecca in the basement.

Tomorrow.

What would be her ethical duty?
