Thomas Anthony Doherty (born 21 April 1995) is a Scottish actor and singer, known for his roles as Sean Matthews on the Disney Channel musical series The Lodge and Harry Hook in the Descendants film franchise.
The episode opens in a dimly lit room as Gustav Fiers walks up to Harry Osborn who is chained to a chair. Gustav tells Harry that he spent his entire life trying to perfect the human race and that Harry was his last chance. Harry tells Gustav he thought this was about stopping Spider-Man and becoming a superhero. Gustav plays music and gets up to leave the room. We cut to a flashback of a young Gustav who has just joined Tombstone's team as a person to keep and count all of the stolen money and put it into the businesses that Tombstone has purchased to launder money. Eventually Gustav met Norman Osborn who offered Gustav a lot more money to come work for him. Eventually Gustav started posing as Norman's butler while behind the scenes the two were trying to create the perfect superhuman using animal DNA. Eventually years later Peter Parker was bitten by a spider and became the perfect superhuman which is why Norman was so set on killing Peter so that he could take his body and find out the exact process to make the perfect super spider. After Norman's death Gustav lost his job but that didn't stop him from trying to get Peter as well as make a superhuman the way Norman turned himself into one. Gustav walks back into the room with Harry and offers him a cup of tea.
