Dwight Harrington is a boy in the online version that cheated off Greg in a test. Greg took notice of this and sabotaged him by writing the wrong answers, and when Dwight copied all of these answers and turned it in, Greg quickly changed his answers and got a decent grade. Dwight was caught cheating but he still failed the test and had to go to detention. As consequence for failing the test, Dwight was also pulled aside by the teacher and was told that he's transferring to Mrs. Bunn's class where all the kids that were held back a grade are in.
