Geek Binge: Even though I sort of did it last episode, I thought it would once again be appropriate to compare The Walking Dead Season 3 with Season 2 of the series at the same point. In the penultimate episode before the midseason finale last year, not a lot happened. Sure, Lori finally revealed that she slept with Shane, and decided not to abort her recently discovered child. But as set up, it really didn’t show what was to come about in the (pretty lackluster) midseason finale. Thankfully, “When the Dead Come Knocking” is a MUCH better set up episode than “Secrets.” Even then though…it’s still just a set up episode.
