Okay so hear me out on this one.

Given that zombies have no heart beat


it would make sense that there would be some chemical in a zombie’s system allowing things to move around— glucose for energy, for example, and something allowing the “hunger hormone” ghrelin to be produced in the stomach and moved to receptors in the hypothalamus— despite the lack of actual circulation.

Ghrelin is produced in the digestive tract— when it’s empty, it secretes ghrelin. Ghrelin goes up to the hypothalamus, hypothalamus tells you you’re hungry. Only in the case of zombies, we get this:


My guess is that the propellant doesn’t really know what to do with itself 100% of the time, and sometimes it misses the hypothalamus. In addition to ghrelin and leptin (the “full hormone”) receptors, the hypothalamus is hooked up to the pituitary gland. The pituitary gland is the little guy in control of a decent chunk of the rest of the endocrine system. What concerns this particular topic is its connection to the adrenal cortexes. Stimulation to the pituitary gland by unknown chemicals (in this case, ghrelin, which isn’t meant to be there) can cause ACTH to be released, prompting what is in this case extreme fight or flight reaction.

Still best guessing when I say that the fun little crackly blue light show Laz (and Sam) can do stops the propellent from working. In doing so, they’ve essentially stopped all “blood-flow,” and therefore the production of adrenaline.

Which brings me to my point.

Zombies likely have some form of propellant hormone coursing through them, present in decent quantities in every “living” cell they’ve got.

The ingredients for the serum are:

1. Rare


2. Self-propellant

(I do not have to post that same screen shot again)

3. Discovered after Marianne began working with Davey

(see #2)

What do we know for a fact Marianne did?

Removed an organ.


What color is the serum?


Conclusion: self-propellant tranquilizer is made from zombie flesh.

Additional note: We should fear for Chainey.
