Hello everyone,

OK. I have updated my WA knowledge up to episode #28. And I learned a lot about "Ground Zero", and the "pinstriped suit". This means, that any direct assumption or conclusion I stated in my original post is kind of ...well, you know ... pointless or something ...
Especially anything regarding "riddle #1" about "ground zero" is without any more consequences. Since Saul and Victor were in that place with breathing-devices it is obvious that there is kind of an emission of some sort - gases or something streaming out of crevices at "ground zero". Obviously my assumption about wind-conditions was very poor; because I did not consider the scenario that there might be kind of an opening producing gases constantly, which may become weaker the farther away the gases flow and thus get mixed with the air. Therefore a "fixed" location with the strange effects makes sense.

My wild-card-based guesses around the "pinstriped suit" are to reconsidered as well; because it does not seem to be the average Umbrella-corp-Manager who keeps an eye on a project, but more of a "leader-Zed" of some kind ...

And yet these two things do not interfere with the general question about why there seems to be kind of a difference between survivors or the Zeds. Both things only clarify the situation as such as well as the origins of the Zed-attack.

@Osiris: Cliffs? What did I miss with "Cliffs"?

Looking forward to learning more in episodes #29 to#31 ... Maybe I will need to amend more ...

All the best!
Liam
