  • Arturo is confirmed to be living in Peru.[1]
  • In "Friended! with the Casagrandes", Arturo and Maria are confirmed to be split up, meaning they’re separated and/or divorced.
  • Even though Bobby's full name is Roberto Alejandro Martinez-Millan Luis Santiago, Jr., his father's full name is not Roberto Alejandro Martinez-Millan Luis Santiago, Sr. It is possible Maria was originally married to someone named Roberto Alejandro Martinez-Millan Luis Santiago and gave birth to Bobby and then got a divorce and remarried to Arturo and then gave birth to Ronnie Anne.
    • Or he has a father or brother with that name.
