The bomb being, of course, any attempt at some semblance of logic and sense. I don't care. I love it. Could pregnant Natalie in her bridal gear carry an unconscious Marty through a staffed courthouse, put her into the car, drive her up to the lodge, and drag her into the place, all without stumbling or getting noticed? No chance. I don't care.
Who would care when it gave us a seriously old-school soap scene with a pregnant bride in high-heeled boots holding a crazy lady hostage with a shotgun? Could anyone not have fun watching these scenes? I know I complain about the lack of logic on this show all the time, but when the payoff is good, it's worth the shameful suspension of disbelief. We even got the obligatory crushing-the-captive's-phone-with-the-spike-heel bit:
What's not to love?
As far as storyline advancement, it was nice to see that Natalie saw that her only way out was to come clean (as she obviously should have done months ago). No sense in resisting it on principle just because the woman lording it over her got the information illegally and immorally, but since this is a soap, things just can't be that simple. The tables were turned as Natalie went into premature labor, though she was in denial about it. This allowed Marty to show some doctorly concern, which in turn allowed Natalie to remind Marty that she's not exactly an OB-GYN and, to boot, is in fact a lousy shrink as it is (a line that I'm sure got many cheers in many, many households). But a collapse gave Marty control of the shotgun, allowed her to return the phone-destroying favor (but with a lot less fashion panache), and put her in the big moral decision-making test that daytime loves so much.
From what I've heard around in addition to the comments here, various fans on either side have been incredibly frustrated that this storyline seems designed to unfairly represent one character to make the other look better somehow, but I am not in that camp at all -- both these women are completely in the wrong, hilariously and awesomely. Each has had the upper hand at different moments, and always for the wrongest reasons. I love that it's not some black-and-white moral battle; that it gives us shotguns and bitch-slaps and hyperbolic language and all of that equals pure joy. Which of course means that Marty did not, in fact, have a crisis of conscience that made her an automatic hero. Instead she left Natalie behind.
