It isn't a fancy dinner. They aren't in an expensive restaurant. He's not wearing a suit, and she isn't wearing a dress.
He is wearing his uniform, and she is just in jeans. They are eating quietly in her kitchen. Sometimes they stare at each other, both with scars in their faces and tired, because saving the world is tiring, but worth it.
Maybe it's not the best dinner they've ever had, but sitting with her like this, that's better than many other things. And him sitting with her makes Maria feel complete, even when they aren't speaking.
This isn't the date he promised; but having her safe and sound and with some chinese food it's enough for him...
And Maria has the same feeling.
