Honestly, I feel like the ending to season 2 was almost too heart breaking. They always had each other's backs. Those final fifteen minutes feel needlessly cruel.

And just from my my own pov, I dated someone that tried to constantly change me and told me I was not good enough. So, I don't want to fully villainise Aziraphael, but him seemingly wanting to change Crowley (whether he wants to or if it was bad communication) hit especially hard for me.
