everyone i know was praying for the kid and his mother to snuff it.
what a useless bunch of people these survivors are - no time spent on defences, no escape plan or routes seem to have been pre arranged.
As to the girl with the katana (she is in the comics), why aren't the 2 zombies still trying to get at her? They appeared to be quite docile. (ah this is explained on the walking dead wikia page). SPOILERS HERE: walkingdead.wikia.com
There have been a number of plot changes from the comics too.
haven't read the comics, but WHY don't black ninja girls chained up zombies keep trying to attack her? Ok she appears to have removed the zombies lower jaws so they can't bite, and removed their arms so they can't grab at her, but since every other zombie even severed limbs and heads) always keep trying to attack, why don't hers?
wow what a difference in the group - last episode they were a somewhat disorganised bunch of amateurs, surviving by accident more than their own skills. Now they are elite swat team grade (even "get in the house" Carl. )
