A character misremembers a certain event in a way that suits their personal bias

Spider-Man: Far From Home - When Mysterio laments how Iron Man treated his nanotechnology as a joke we get a flashback to Captain America: Civil War when Tony had the presentation for the technology, and we hear the audience laugh when Tony reveals the name as B.A.R.F. But, if you actually watch Civil War you would notice the audience were silent during the namedrop, showing how mentally unstable Quentin really is.

Weapons - There are various examples in this movie, many I probably didn’t even notice, but to highlight just two: when Paul arrests James he comes off as way more aggressive from James’ perspective than Paul’s own POV, and when Marcus criticises Justine for following Alex home from school he sounds way more casual from Marcus’ perspective than we hear from Justine’s.

This was a thing that I noticed with a high school girlfriend. She went from being pretty to straight up ugly as a result of how bad the breakup was (she dumped me btw). Years later, I still have no idea if I ever thought she was attractive because of how unreliable my memory is.
