At the start of this week we learned who would play Cory and Topanga’s daughter Riley on Girl Meets World, the highly anticipated Boy Meets World spin-off from Disney.

Since then we have new updates to share. Riley’s rebellious best friend Maya has been cast, and producers started to search for Cory and Topanga’s son!

Maya Fox, Riley’s best friend, cast

Sabrina Carpenter, 13 years old and pictured right, will take the role of Maya Fox. She will also appear in the Fox comedy The Goodwin Games later this year.

The character of Maya, a series regular, was described in the casting call in the following manner: “Maya is Riley’s best friend and does not share Riley’s optimism. She is far darker and less trusting of the world. She is an only child and has never known her father, which immediately makes her relationship with both Riley and Cory Matthews very important to her although she’d never admit it. She is not a good student in school, but is a wonderful student of life and absolutely magnetic in attracting or intimidating the people in her sphere as she cares to.”

Producers search for Cory and Topanga’s son, plus two new characters outside the family

Character Elliot Matthews is 13 years old and according to EW is described as a “thinking man’s jock.” The casting call went out today.

Elliot is “good looking, well built, funny and insightful in his observations. Good hearted except for his dedication toward using Riley (Blanchard) as his wrestling practice dummy. His parents worry that he has inherited the ‘Eric Matthews Algernon’ gene and will lose intelligence as time goes by.”

Next up is Tristan Friar, between the age of 12 and 13. Tristan comes from Texas and “seems actually possessed of ethics, common sense and a value system making him immediately alien to everybody else except Riley, who believes it’s the value system that attracts her to want to be his friend even though he’s too good looking for her to look at.”

Finally there’s Shamus Farkle who’s between 12 and 13: “Future world ruler. Riley’s rebellious best friend Maya is his nemesis, Riley gets between them to save his life. Farkle is wildly attached and protective of both girls and loves equally that Riley doesn’t make him miserable and Maya does.”

Girl Meets World will soon be shooting its pilot.

Thanks, EW.
