Although Slade Wilson has been written out of Arrow, we may see Oliver Queen face off with a character with a strong connection to the master assassin.
"I would say if you are looking for iconic fights there might be a fight coming up with another Wilson," Arrow star Stephen Amell told an audience at Wizard World Louisville. You can hear the comment around the :31 minute mark in this YouTube video.
In comic books, Slade Wilson has three children. His oldest, Grant Wilson, followed in his father's footsteps as Ravager, an enemy of the Teen Titans. His middle son, Joseph Wilson, possessed mind control powers and was both an ally and enemy of the Teen Titans as Jericho. Finally, his youngest, Rose Wilson, became the second Ravager and continued her family's tenuous relationship with the Titans. In the"New 52," she is a full on supervillain. All three children have connections to H.I.V.E., the criminal organization fronted by Arrow season 4 antagonist Damien Dahrk.
On Arrow, Deathstroke previously mentioned a son named "Joe," which points to the idea that it could be Jericho who squares off with Oliver at some point in the future, though nothing has been confirmed.
Arrow airs Wednesday night on CW.
