After the zombie attack that concluded last week's episode, this week's The Walking Dead deals with cleaning up the bodies and emotions left strewn around the campsite. Eventually, the gang gets motoring to the CDC for answers!

The Centers for Disease Control and Prevention seem like a pretty good place to go in a zombie apocalypse. Luckily, our ragtag band of survivors are just a hop, skip, and jump away from this oasis in a zombie wasteland. When they arrive, things get tense.

Who is the mysterious man in the CDC? Apparently, he is a scientist who is not having the best day.

Tough break, science guy. You try to be careful in the lab, but one way or another, you end up destroying the zombie tissue sample that will help end the zombie outbreak. With all the science and bunkers in this episode, this show is turning from The Walking Dead into The Walking Lost.
