(spoilers for this ep)
I think that was some of the loudest foreshadowing I've ever experienced.
Carol:
"Sometimes you have to make difficult choices."
"When the time comes, you'll have to do what it takes to survive."
"You have to be prepared to do horrible things sometimes."
"In this world, you're confronted with ugly decisions."
"One day, to survive, you'll have to do something horrible."
"I'm going to have to put your sister down."
I liked the episode, though. Totally agree with 03 that psycho girl's craziness was enhanced by her less-than-perfect acting. She and her sister are still better actors than alcoholic girl.
But yeah, Carol was obviously the highlight. If there was a performance better than that in this show I think it would break the fourth wall. Tyrese was great too, and their characters are surprisingly good. Glenn, Maggie, Carol, and Tyrese are holding the show together right now, and I love watching all of them. Carl and Beth can fall in a pit of zombies. (Beth in a drunken stupor, Carl chasing after a butterfly or something. Natural selection.)
