In the first mystery of the series (part 5), Alex speculated that there would eventually be a big mystery as to who Ghostwriter really was. The series ended in 1995 due to lack of funding, and the speculated episode never went into production. The writers had considered eventually revealing him to be a slave, possibly Jamal's ancestor, who was killed for teaching other slaves to read.

According to Blaze Berdahl's (Lenni Frazier), Facebook page, co-star David Lopez (Alex Fernandez) was her first boyfriend.

Each time that Jamal realizes that someone else besides him or Lenni can see Ghostwriter he says "You can see that?"
