I loved Sophie’s character. I wish she stuck around longer. And watching this show as an aunt who would do anything to protect my niece and nephew, Sophie’s death HURTS. All she wanted was to bring Monique back to life. She got that and tried to get her out of the town that is about to be a war zone..and the person she loves most brutally kills her. I HATE Monique but the actress does a great job!
How does the fetus get oxygen in the blood before birth if they don't share a circulatory system? Oxygen, nutrients, and CO2 / waste removal depends on the mother for most of the pregnancy. We already know that the placental barrier isn't perfect. Foreign fetal cells have been found in the pregnant woman's circulatory system years after birth. I view it as a pressure regulation mechanism more than an actual barrier. We know certain antibodies, gases, and nutrients pass through this so-called barrier. It would be foolish to conclude that it performed perfectly in preventing fetal blood from passing into the maternal circulatory system, in my opinion.
