"Where are we going?" Vision asked, as Eva dragged him by the hand through the crowded avenue. "Central Park?"
"For once, no. This is me being your friend, for once, instead of you being my friend."
"I… I'm not quite sure I understood that," Vision said.
"Not sure I did, either. We're here." She gestured to a large and beautiful white stone building fronted by four pairs of white pillars, with shallow steps leading up to them. People gave them funny looks as they walked past, but this being New York, they didn't say anything.
"The Metropolitan Museum of Art," Vision observed, eyes studying the banner across the central doorway.
"Yeah. Everything you want to learn about humanity is within those walls, V. Love, loss, war and peace, weird naked statue people… every artist is just trying to capture what it is to be a person when they work, however they do it. If you want to understand us, this is how." She inhaled, having said all of that in one rushed breath. "Also, the Roof Garden is the best café in the city. They even do tea." She gave him a hopeful look.
His eyes went from the museum to her, and he broke out into the same smile she had seen when she first served him. "Eva," he said, "this is wonderful."
"I do my best," she shrugged. "Hell, I even bought a ticket for you." She knocked her shoulder against his arm affectionately. "You want to go in, Oompa-Loompa, or just stand there gawping?"
"Where would you like to start?" he asked her, as they climbed the steps.
"Sweetheart, this is your day. You choose."
"Please," he said, and she rolled her eyes.
"Fine. Let's go to the gothic bit."
They had arrived just as it opened and were practically the last people to leave; Vision would stand motionless in front of the pictures, a little further back so he was not obstructing anyone else's view, with an expression Eva had never seen before on anyone else, ever. Eva, for whom art held very little interest after a prolonged period of time, spent most of the day sat on a variety of uncomfortable benches either listening to Tchaikovsky in her earphones- it seemed to suit the area so well- or watching him with a small smile on her face.
When he was finally done and the sun had given up to city to night, they sat in the half-full rooftop garden with a pot of tea between them that only she drank, and she grilled him about the art- not just what it was, but what he liked, what he didn't like, what made sense to him and what just seemed ridiculous.
"Every person's gotta have opinions," she told him sagely, and eventually they figured out he seemed to prefer the Hellenistic and Greek stuff the most. Eventually they were shooed out of the museum, and she took him back to her flat and they watched Bo Burnham gigs- "the pinnacle of human comedy, V"- until she fell asleep on his shoulder and he seemed to enter a sort of meditative state. Neither of them said it aloud, but it was the best day either of them had ever had- no aliens invading, no getting catastrophically drunk, just friends.
Really, really weird friends.
A/N so I'm trying to keep this (and Finding Bucky, and my other MCU fic I am yet to publish) completely canon-compliant, but I'm very paranoid about timelines- specifically, that Civil War will be set less than a year after Age of Ultron. So if it is, I will a) be writing a strongly worded letter of complaint to Stan Lee, and b) be making a slight alteration to canon in order to make timelines work because, let's face it, we all want to see Eva do Christmas with the Avengers. So regardless of what time frame Civil War is actually in, in this universe it will be set a year after AoU. Aside from that, Coffee Run can 100% exist in the MCU without any problems.
