This fourth season of “The Walking Dead” has started with a serious bang! From zombies falling in from ceilings, zombie pets, to burnings, everything can and should be expected. The next episode in the series, “Isolation,” seems to bring even more horrors to the surface:

“As one group leaves the prison in search for supplies at a local college, those who stay must deal with recent losses while preserving what remains.”

We’ve got some exclusive pictures from the upcoming episode! The pictures show Carol (Melissa Suzanne McBride) and Bob (Lawrence Gilliard Jr.), Daryl Dixon (Norman Reedus) and Michonne (Danai Gurira). Take a look at the stills below and try to guess what has them all looking so conflicted. (The easy answer is that it has something to do with zombies, but it could also have something to do with that super virus going around.)

“The Walking Dead” stars Andrew Lincoln as Rick Grimes, a former sheriff’s deputy who wakes up in the middle of a zombie apocalypse. He then becomes a leader of a band of human survivors trying to fight the surrounding zombies. The upcoming episode “Isolation” will air on AMC Sunday, Oct. 27 at 9/8c.
