This was beautiful, and I love every little bit of it - from them having a last go of it when it becomes clear to Sam how their story's going to end, how he gets their affairs in order by leaving small pieces of their lives and legacy with other people to carry on (Moxie, money from the house, Ruby's knife). I love the small detail of Sam already knowing what a gun in his mouth feels like. Everything is just heartbreakingly beautiful. But I think my absolute favorite thing through all of this is that even with every memory Dean lost, he always remembered Sam. <3
