That "what is left, Ana?" interaction still gets to me. A moment of rare solemnity and vulnerability for both of them. Ana cares so much, it's so soft!
"The world doesn't want us anymore, at least I can realize that" is such a terrible line, especially because they lowered crime rates. What the world wants & what it needs are 2 different things.
It's been my headcanon for a while that even though Ana had a husband Sam and daughter Fareeha, Reinhardt loved and never stopped loving Ana through the decades. Ana keeps a distance but Reinhardt is unashamed of his feelings.
