I hope there are no more pregnancies.
As much as i agree, I also think as a show, they need them.
Part of the show is OMG ZOMBIES ARE EATING YOUR FACE...and the other part of the show is this group of people who are trying to not only survive but to continue life.
This walking dead is a new normal - and with any new normal, you have to learn to live in that newness. Part of that is the creation of new life.
As a writer, you can not ignore life.
