The in MCU films, you might need to do a bit of reading to catch some of the easter eggs. This means looking at random letters or logos that hold a certain significance in relation to Marvel and its characters. Here, we can see a picture of Hawkeye’s new-born baby in Avengers: Age of Ultron. At first glance, it’s just a baby, but the writing on his shirt reveals a lot more.
However, upon closer inspection, you’ll see that the printed shirt reads Nathaniel Pietro Barton. Where does the middle name come from? From Quicksilver! He’s also using Skype for some odd reason.
