also did the whistle thing that stopped Yelena remind anyone else of the Maarthaaa scene in BvS? it wasnt as cringey as a Maarthaa scene especially after the reminder released in the past week that when Yelena visited Natashas grave she whistled to her sister (but didnt get a reply). That they released that 'director commentary' now and then we get pay off in Hawkeye giving the return whistle, just goes to show how tightly crafted and integrated the MCU is and Hawkeye has particularly good writing
