8/10 A cool moment and a nice throwback but as for the quote, it's not very epic out of context and endgame had other better scenes, don't get me wrong this is a good end to Tony's journey but Tony is far from my favourite MCU character.
Madge: Lily and Cyril's father, my husband, is dead and they don't know yet, because if I tell them now, then Christmas will always be what took their father away from them, and no one should have to live like that. Of course, when the Christmas period is over, I shall. I don't know why I keep shouting at them.
The Doctor: Because every time you see them happy, you remember how sad they're going to be, and it breaks your heart....Because what's the point in them being happy now if they're going to be sad later...The answer is, of course, because they are going to be sad later. Now, we'd better get downstairs. I think they may have found the main sitting room. - Doctor Who
