 The plot of Monsters University details Mike and Sulley 's first meeting , but this created a continuity error from the first film in which Mike tells Sulley " You 've been jealous of my good looks since the fourth grade . " Director Dan Scanlon said he had a dilemma with this line during pre @-@ production , but he believed it was best if Mike and Sulley meet in college because , " we wanted to see their relationship develop when they were adults . And we also felt like college is so much about self @-@ discovery and figuring out who you are . " He added , " It felt like the perfect place to do this , but we had that line . So we tried versions where they met young and then we skipped ahead to college . And we knew we didn 't want to make Monsters Elementary . " Scanlon said during pre @-@ production that , " Pete Docter , the original director , and John Lasseter ... finally said to me , ' it 's great that you 're honouring that , but you have to do what 's right for the story . ' So we made a tough decision to just have them be in college and put that line aside . " Scanlon later retconned the line from the first film as " an old monster expression " , saying " That 's what monsters always say to each other . "
