'The Walking Dead' Season 4 'Isolation' clips reveal who is already infected

"The Walking Dead" isn't wasting much time escalating its virus storyline. Be warned, spoilers from Season 4 episode 3 "Isolation" are included in both clips and this article.

As the above clip shows, one of the central cast members in the AMC hit drama is already infected with the virus. Sasha looks pretty ill at this point as she bumps into Hershel and Glenn on her hunt for Dr. S. But when she goes to find him, all she discovers are other even sicker survivors and one who has already turned into a walker.

It's no wonder then that Sonequa Martin-Green was gushing to Zap2it about the virus storyline at "The Walking Dead's" Season 4 premiere. "I think this virus is the perfect example of keeping it moving and keeping it unpredictable and keeping this sense of danger alive. Although it might seem like we have a semblance of security, we don't," she said at the time.

The other clip, below, shows Daryl, Michonne, Bob Stookey and Tyreese driving through the woods when they suddenly hear a voice coming over the radio. Unfortunately for them, that surprising voice distracts them from the fact they've driven straight into a massive horde of walkers. That explains what that car scene in the featurette is all about.

"The Walking Dead" airs Sundays on AMC at 9 p.m. ET.
