It only seems to be directly related since it's the most logical deduction. The mother and baby are indirectly related. We can trace why the baby died by the mother dying, but the mother's death didn't cause the baby to die. Someone else could have stepped in to take care of the baby for example. There's only a direct line if the baby actually dies and even them its only direct because none of the other lines were followed. With the nukes, where they land people die. They most certainly would not have died if the nuke hadn't happened. That's direct. I concede, it might be possible...but I highly doubt it.
*facepalms* I know I can't spread a virus. I don't need too. Yes, I know it will take time and planning, but what do I care? I have nothing better to do, and I will greatly enjoy the fallout. A basic plan would go something like this...
1. Choose a disease I like from my previous experiments
2. Write a few names located in one area along a coast with a high population and tourists. airports, ships, etc.
3. Write more names, staying in that area but shortening the time.
4. First death outside of area occurs...by still close. ie. no airplanes, ships etc. needed. probably cars.
5. More deaths inside and outside of area, first death outside of "country"
6. I'm not going into great detail here. This keeps going on...more and more deaths...more and more places...panic sets in. I have no intentions of letting up. I know I will need to continue to write names for decades, but I have nothing better to do so here we go.
Killing everyone on my own would be boring. Much more fun to watch the masses kill each other out of fear. Fear is very easy to manipulate.
Did you ever look at a picture of yourself and see a stranger in the background? Makes you wonder how many strangers have a picture of you.
