As Greg mentions, he is very smart because of reading college textbooks and scientific journals. Greg often leaves his homework to him, but this ends him up in harder classes.
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.
- Greg mentions that Frew is in third grade, making him either 8 or 9 years old.
- Frew is based off of a real-life person.
