I rewatched Captain America: Civil War last night and when Peter and Steve are talking during the airport fight scene, Peter says
“He also said I should go for your legs” and he kinda chuckles
and the only thing I could think of was that Peter saw that vine “How did you take down Captain America?” and the guy responds in a Russian accent, “We shot him in the legs because his shield is the size of a dinner plate and he’s an idiot”
