Cutest (and most reasonable) thing ever: the way Sam and Dean searched for listening devices in the Bunker. They took the places they knew best. Dean took the kitchen, picked up every jar and shook every single canister. Dean knows the kitchen. Whether he’s there to grab another beer from the fridge or make a few burgers, he’s comfortable there. He may even have filled and organized all those jars, just like he did with his bedroom, taking the things he found appealing and making them accessible. Sam, on the other hand, took the library. Sam, who has actually started digitizing the Bunker’s archives, is the most likely to be intimately familiar with any potential hiding places on the shelves. They both took common areas that were their sanctuaries, operating under the assumption that those places were no longer safe.
We should extend a challenge to Andrew Dabb next season. For every episode, allow a group of spn fanfic writers to go head to head with the writers on staff. Give them both the general storyline and what elements it needs to have and see who turns in the best script.
