How short it is isn't the point. :)
A pregnant woman has ultimate power, to be creating life inside of her... and yet at the same time she is ultimately powerless to her own body, as well as to both the man whose seed grows inside her and to the baby whose very existence violates her body. Likewise, giving birth is the ultimate act of both female empowerment and helpless surrender.
What's wonderful here, removed from the context of the storyline leading up to this point (we haven't seen it) is how quickly the power changes, literally from one frame to the next. She goes to her healer, gorgeously swollen and panting, needing him to carry her through a natural process happening within her own suffering body. You can't get anymore helpless than that.
But when she sees he's not actually helping her? All bets are off. It was her body long before it became her baby's, and (suddenly) it is only by her permission that the baby has been allowed to live and grow inside of her all this time (tell me if she doesn't look capable of aborting it herself at any time had she wanted to). Her body comes first, and she knows it, and there never was any question of it, and now both her healer and her baby have crossed the line. So what does she do? She tears off her baby's head, strangles her healer with the baby's umbilical cord, and presumably marches away without any bed rest whatsoever.
No doubt this is how (the more extreme) pro-lifers would love to see feminists portrayed. And yet you can't help but love it regardless. This is the real dark side of female empowerment. Survival of the fittest.
