As Greg mentions, he is very smart because of reading college textbooks and scientific journals. Greg often leaves his homework to him, but this makes him end up in harder classes. Frew is a fast worker and can get many pages of homework done in 15 minutes.
Apparently, Frew is forced to become smart since his parents make him wake up every morning at 5 A.M. to study. He cannot do normal things like play laser tag because his parents say it is "a waste of time". It is possible that he could have been making up a sob story as he actually enjoys his work.
Role in Old School
As it is shown as before, he was Greg's, Homework Buddy. When he and Greg met, he realized he is smart and could read scientific journals and college textbooks. Greg then suggesting doing his homework for him, only to get in harder classes and being rewarded, like going to the Old-Timey Ice Cream Parlor. Frew also finishes work very fast, like how it took Greg hours to finish his work, but with Frew's intelligence, Frew got done with it in 15 minutes.
Greg then meets up with Frew later on in the book, when the town was cleaning the park, Greg decided to go with him, along with Frew and Billy last. The trio manages to outrun the Girl Scouts, but they got caught when he saw Susan's car and the Girl Scout's cars. They then scolded at the trio, so then Frew explains the story, and he burst into tears. To get himself out, Greg manages to pass the blame to Billy, probably the fact that Billy got caught stealing a pack of sour gummy worms. He was never seen again in the book.
- Greg mentions that Frew is in third grade, making him probably about 9 years old. However, due to Frew's apparent intelligence, it is likely he could have been placed ahead, meaning he could be even younger than 9.
- It is unknown why Frew would want to play laser tag in the first place.
