Chapter 39-2 Chemical Reactions

Damn!
Saul and Tanya showing signs on infection is throwing me for a loop.
I've always been a proponent of the family immunity theory and I still feel mostly certain that things are going to turn out alright for them. But I'm starting to get that small little twinge of doubt that this could turn nasty before the end.
There is one thing sticking in my mind. I remember Saul noting in Chapter 28 that the zombies might not even be able to survive the haze at Ground Zero. So, if we do end up seeing Tanya going there to test the air and she ends up being immune to the effects the way Saul was, that might be an indicator that their high Keratin 18 levels are signs of something other than slow infection.

As for the whole Keratin 18 thing, in general. I only took a quick look at what it is, but what I found is that it is a molecule found in epithelial tissue, and that it is sometimes used to detect circulating tumor cells in blood.
So I'm thinking maybe the high levels of K18 in the blood during the first stages of infection could have something to do way the zombies skin thickens.
And circulating tumor cells just makes me think of how the behemoth was full of tumors. I'm no sure, I'll leave the rest of the digging to our resident researchers, but my mind's tingling.

So it's a tumor? *Queuing Arnold*

Anyway, so maybe we are looking for a cancer "cure" that cause the outbreak. We can look up chemical used in cures to find the answer about our mystery chemical in the two bottles.
