Listen, Tom Holland has done enough real spoiling that we don't need to r-e-a-c-h and pile on. The Spider-Man: Far From Home star was just on The Graham Norton Show promoting his second Spider-Man movie. That's his job. As part of his job, he mentioned a major event from Avengers: Endgame. Not only is that also part of his job, it's not even the first time he's been on a talk show openly discussing plot points from Endgame. (No one else watched the Spidey cast on Kimmel?)
