I think even some hardened sorts were at least a little sad for Steve and Peggy. Would you like to see it followed up on? According to deleted Avengers material, Peggy is alive and living in London. Would you like that to be disregarded or do you want to see Cap visit old Peggy, perhaps have that dance they talk about? I think I'll be in the minority that says; she died a while ago. She got married to one of the Howling Commandos, had a long, fulfilling life, and died happy.
