How Anthony Mackie found out about Falcon-Bucky ship (this is just a fan theory):
One day Mackie was bored during lockdown and decided to google some fan-art of his latest show Falcon + Winter Soldier, he saw lots of nice artwork of his character Falcon with his best friend Bucky, he thought “awww, my fans are so sweet”, but as he scroled down his expression of joy turned to one of horror, scattered between the innocent fan-fictions were the lewdest of the lewd, images of Falcon doing ********* and ******* with his bro Bucky, Mackie shut his laptop unable to unsee what he’d just witnessed, his only relief that he haden’t searched for that fan-art toghether with his kids
