All I can say is wow.
The zombies have a parachute regiment!
And the zombies on the roof never hit one of the many,
many soft spots in their aimless wanderings until the living people showed up, and they never all gathered on one side of the roof - much less fell off - attracted by some outside noise . . .
Also notice how some of the children think zombies are
cute and deserve
names, and think it's OK to wave at them and attract them without killing them.
We'll see how this plot line - and the kids' interaction with Carl - play out over the course of the season.
