Old man Dean! And his young man :3
I have a huge soft spot for older Dean/always-young-angel Castiel. There has to be a little bitterness in my curtain stuff. I like the sadness of it, but I also love the idea of Castiel loving Dean no matter how he changes over the years.
I also firmly believe he would be there when Dean dies, and leaves for heaven mere moments after him. lalala you can’t tell me different
