"Just the fact that there's motion and sound, took me a long time on Walking Dead to get used to the fact that in television, characters don't have to say things. In comics, people have to say I feel this way, or I want to do this, and you can do so much with gesture and movement and facial expressions that you can do sometimes facial expression stuff in comics, but you can do so more if somebody can move around without actually speaking. That leads to a different style of writing between the two mediums."
