Yeah I didnt understand the disease "retreat", nor the bolting his shoulder or trying to asfixiate but I guess we must judge that according to other things showed in the show and its lore. Its pretty clear that it makes no sense to us.

Couple of things I didnt get. How is a weapon that needs a steam furnace for 1 shot gonna help and why did they say that the ones suspected of infection must stay 2 or 3 days in quarantine and this time the infection happened in seconds to the MC, in minutes to the priest guy and the citizens.

I actually liked how the "guard" were just common thugs and even the lord couldnt force himself to stop them. Thats pretty much real life like.

Also how the hell could the girl severe a head with a blade that doesnt seem more than 2 inches long? That was unnecesary bullshit right there. You need several hits or a blade at least the same width of the neck to achieve that in any universe that has the slightest sense.
