I love how much DTA plays on the actual episode.
The unsettling idea of someone clearing a space or the city of crotes to open a path for Dean? Or maybe it's the tiny fact that they want Dean to do something and they knew Dean would connect the dots for them?
Also, here you can visualize how much DTA Cas was trained and conditioned by endverse Dean. Of course Cas sees the absence of threats where no one else did —his Dean did that too.
