go on take the baby and run

While I understand Bridget's anger towards Agnes, I don't know that it's wise of her to unload all that bitterness and resentment while the woman is carrying her child. What's to stop Agnes from taking the baby and running?

I think Bridget needs to unload her anger on the person who deserves it: Nick. The man is a consummate liar and Bridget knows that he has kept secrets from her in the past. That's why she's so bitter and angry. She knows that a total stranger was able to convince her husband to keep secrets from her and she knows there has to be a damn good reason why: Nick has feelings for Agnes. Why else would he put more stock in a stranger's wishes than his own wife's?

When all is said and done, I can't stand Nick's character. He's as wishy washy as Nick Newman, bouncing from one woman to another. Evey one is the love of his life and none of them last longer than a year. Hell, most of them would be lucky to last a year, including Bridget.
