Error in beginning of movie
If this was posted, I didn't see it, so I apologize, but:
"Almost nine months later" after the opening scene is a blatant mistake.
We already know that both women are pregnant, which no one really knows before 1.5-2 months into pregnancy. For the sake of argument, let's say they both somehow found out at like six weeks. Then it should be roughly seven months later.
In reality, it would be less than seven months later. So, semantics or not, "almost nine months" is a mistake.
