One of the most heartfelt scenes in Avengers: Endgame was the exchange between Natasha Romanoff and Clint Barton, as they both try to make the sacrifice for the sake of half the universe. Natasha is the one who takes the leap of faith and leaves behind her closest friend to carry the weight of the Soul Stone in his hand. Her legacy lives on through Yelena Belova, who we were introduced to in the solo Black Widow film and is set to return in Hawkeye. She is confirmed to appear in the upcoming series and it seems like Clint Barton hasn’t quite gotten over the events either.
In an interview with the Evening Standard, actor Jeremy Renner talked about how Black Widow will play into the story beyond just the appearance of Belova. It seems that we’ll also use this series to explore Barton’s grief from losing her, especially as he did it all for the sake of his family that he once again has to leave behind to look after Kate Bishop and her shenanigans.
There are giant reminders of Natasha in this series. Reminders of things that tie into losing somebody and reminders of all that beautiful things that come with a lot of pain as well.Jeremy Renner
It makes sense that this death would still hang over his head, as he was the one that had to let go when they were hanging from a cliff on Vormir. Belova’s appearance in the series will definitely bring back the dark reality of that moment and once again bring him face-to-face with the consequences.
