3-7 The Lamb

When the villainous Kenny, an ancient immortal sociopath trapped in the body of a young boy, worms his way into Mac's home, the gang must uncover the little jerk's murderous past before he turns on Mac and Anne. The Rewatchers discuss how the opening shots blunt the episode's tension (like a brick to head), meet the least threatening nerd immortal since Michael Moore, and almost throttle each other to get their hands on a totally rad "skate."
