In response to why the hospital and police station still had lights on and functioning elevators in the previous issue, Kirkman states, "Places like police stations and hospitals would have back up generators and I'm thinking for the most part that power would remain available until something went wrong."

Kirkman also writes he is not officially saying all the Woodbury survivors were killed, but "the prison is dead to me. I've moved on and so have the characters."
Kirkman and Sean discussed that the war, up to this point, had been about a week and a few days, with #115 and #116 being one day. #118 being approximately a week, with all the quick, smaller attacks on the outposts. And then #119 and #120 being another day.

It is explained by Kirkman (regarding Magna not finding any survivors during seven months on the road) that anyone who made it that far into the apocalypse, most likely did so by forming community of survivors who are far away from each other and hard to stumble upon during seven months of traveling.
Kirkman explains in the letters that he prefers comic covers that are "striking" and "a surprise" rather than having an accurate cover or one that reflects what is happening in a particular issue. This explains why so many issue covers do not contain anything in the story or are misleading.
Kirkman jokingly says that each time a reader asks about Michonne, he pushes her reappearance or death confirmation back by two issues. It is also mentioned that issues without Rick might become a trend from now on.
It is revealed that Negan was a used cars salesman before the apocalypse. Robert Kirkman alludes to the possibility of releasing a set of maps of the comic series, showing faction territories and other things.

It is explained that some characters are aware of what happened in the past, such as Andrea knowing Carl killed Ben and gives a glimpse into what to expect in future issues.

Robert Kirkman also claims that he thinks that Rick's physical limitations make him a better character.

Robert Kirkman confirms that there is only 1.6 million people still alive in the world. There are vast dead zones and Montana only has a population of ten people. He later rectified this, saying it was a joke.
Sean Mackiewicz says that there will be no snow in the following issue.
