Last night's all-new 'The Walking Dead' episode "Walk With Me" may not have had any jaw-dropping action sequences the way the first two episodes of the season did, but still introduced us to some important aspects of the third season. Not only did we get re-introduced to Merle, but the psychotic Governor and his seemingly idyllic Woodbury as well! So now that we've seen both sides of season 3, what's going on back at the prison? Two new clips show dangers afoot!

The terror never stops in 'The Walking Dead,' as even within prison walls new horrors can approach from any direction. The survivors may have saved Hershel's life and cleared out most of the walkers, but were those the only threats? As new clips from next week's episode "Killer Within" reveal, the prison may not be as safe as it looks!

Of course, not everyone seems too worried about the zombie apocalypse to pass up a little guard-tower nookie, as in the case of Glenn and Maggie in the first clip. After all, could you resist Lauren Cohan? Meanwhile in the second episode, it seems that the prison is more functional than Rick and his group gave it credit for, but that might not be such a good thing, considering. Plus, who could have activated the power?

Check out two new sneak peeks from next Sunday's all-new 'Walking Dead' episode "Killer Within," and give us your predictions in the comments!
