An enjoyable, but odd episode.
The wandering trio had some interesting moments, but on the whole, it didn't make a lot of sense. Did Sasha really think that she and Bob could just "settle down" in some random abandoned warehouse by the train tracks? Surely, after her time at the prison, she understands that a larger group and sustainable resources are fairly critical to long term survival?
And zombie behaviour is getting more and more difficult to understand. Maggie was trapped by zombies so she just lay on the ground and they forgot about her? That was convenient. And the zombies in Daryl and Beth's mystery house were pretty effective at walking down stairs. With their feet shambling, I would have expected zombies to fall down stairs or have to crawl down them instead of walking down.
And the aforementioned mystery house was just odd. So well taken care of, but without any clear defensive measures. The front door was just unlocked and the food wasn't even hidden. The corpses ready for burial were also odd. It didn't strike me as a "trap" for people. Surely that would be too ineffective. What are the chances of someone stumbling along that house and deciding to stop there long enough for whoever was responsible for watching it to report back to their group? At the same time, if someone (good, bad or crazy) was living there, the fact that they left it unlocked for such a long time was equally odd.
And if it was a trap, then their actions were odd. Fair enough, they appear to have cut-down Daryl's early warning system and somehow lured a whole bunch of walkers to the front door without being detected, but wouldn't the result of that more than likely be two dead people and a formerly safe and clean "trap" house that was now full of zombies? Even if they thought that Daryl and Beth would escape, how did they know that they would run to the road to be there ready and waiting with a car. With all the zombies around, they could have been forced to run in any direction.
Wouldn't it make more sense to lull anyone who visits the house into a false sense of security and then attack them? Or to drug the food supplies so that once they've eaten, they're easier to kidnap for whatever nefarious purpose.
I guess the zombie apocalypse makes some people crazy, but there seemed to be far too much at risk for a minor and unknown reward for the entire house and zombie attack to be part of a trap. Not that I have a better explanation for the events.
