It is highly likely that Freddie is the product of incest parents. It was revealed by Dan Schneider that Freddie's father's name was Leonard Benson, meaning Freddie's surname is derived from his father. It was also revealed that Freddie's fencing skills are passed down from his ancestors who were known as the 'Fencing Bensons'. However, it was noted that Freddie's mother Marissa also acquired her fencing skills from the Fencing Bensons, despite the Benson surname belonging to Freddie's father Leonard. This means one of the following:

1. The Fencing Bensons are maternal ancestors of Freddie (from his mother's side), and Freddie's father shares a surname with his mother (maiden name) by pure coincidence.

2. Freddie's parents are related and are both descendants of the Fencing Bensons, meaning Freddie is a product of incest parents and therefore explaining why Freddie is such a strange and troubled human being (exemplified by his sudden Spanish outbursts).
