omg I guess we have completely different tastes here! I really loved that 4th wall breaking ep, I thought it was fun and also in the past I've had trouble with people (not even spn fans) saying the fans shouldn't ship this or that and I loved how the episode made it explicitly clear that the creators encourage such stuff and everyone to make their own interpretations. That felt like such a great 'screw you' to the haters so I kinda just loved it for that :D and I also really like Crowley's mom, I love how much Crowley the season has had, and of course the Mark of Cain stuff has been pretty interesting, if maybe a bit too drawn out, this far.
