Good episode!
I loved Sam & Dean's banter banter about Dean's undwear and Dean using Sam's secret shampoo. I'm glad Sam told Dean about working with the BMOL too and Dean saying they work them as a team. Omg Dean banter with taking care of Baby and then Dean's reaction to seeing Baby's windshield cracked from the hellhound!
Sam & Dean looked hot wearing those glasses!
I also loved seeing badass Crowley get the best of Lucifer too!
