As far as Sophie giving birth and being only 16, young women having been doing that Neanderthal times. Not the best way, but it happens. I would hope, though, that the closer the time comes, the more she get nervous about it. That could prod her to seek medical attention. If she started getting Braxton-Hicks contractions maybe, would that even be anything she would know about? I only knew about that when my friends in my 20s started having babies. Did That Man rush out and buy her a copy of What To Expect When You're Expecting? At 16, I had only the vaguest ideas of what being pregnant was like. I knew much more about what caused it.
How does Western Union work these days? Could someone send him money that way, if he had good enough fake ID? How thoroughly was the area around his hometown searched? Maybe I have a vivid imagination, but I'm having thoughts of an abandoned cold war bunker or something similar. Pre-stocked, ready and waiting for them.
All is MOO
