In a recent interview, Manu Bennett suggested that Slade's son might have other siblings, and asked fans to dig deeper for clues in the DC comics to appreciate that complexity of the storylines in Arrow.

The Huntress to Fight the Canary in Episode 17?

Bennett, who plays Slade, spoke to TVLine about his character arc and how the show might ravel in relation to the DC comics.

Audiences know little about Slade's son, Joe, but Bennett brought him up while talking about why Slade was completely broken up by Shado's death.

Batman Super Villain Harley Quinn to Be Part of the Suicide Squad in Episode 16?

'You have to remember, Slade Wilson has also got an ex-partnership and a son out in the world there somewhere. And the son's potentially got siblings in some scenario that hasn't yet evolved into the storyline,' he says. 'People have to think about more than the layers of what is being shown in each episode. They have to find clues in the DC Comics history, to maybe even piece together more of what Slade is festering upon."

The synopsis of the next episode, called Suicide Squad, of season 2 suggests that the Slade-Oliver feud will be dragged on for a while. Oliver will have to prepare to combat his former friend, who has sworn to destroy Oliver and his family.

The synopsis also reveals that Diggle will be helping Amanda and A.R.G.U.S. to take on a warlord from Afghanistan, but he will end up finding himself in a sticky situation.

Here's the official synopsis:

"Following Slade's (Manu Bennett) return and his promise to make good on his threat to destroy Oliver's (Stephen Amell) loved ones, Oliver focuses all his energy on preparing for battle with his former friend. Sarah (Caity Lotz) tries to help but, fearing for her safety, Oliver pushes her away. Meanwhile, Diggle (David Ramsey) is recruited by Amanda Waller (guest star Cynthia Addai-Robinson) and A.R.G.U.S. to stop a warlord (guest star Lee Majdoub) he knew from his time in Afghanistan. Always the soldier, Diggle agrees to help. However, he's not prepared when Amanda introduces him to the rest of the team -- Deadshot (guest star Michael Rowe), Bronze Tiger (guest star Michael Jai White) and Shrapnel (guest star Sen Maher), all criminals he and Arrow helped put away. Lyle (guest star Audrey Marie Anderson) defends the team and explains the world is a complicated place, but Diggle isn't sure he agrees. When the mission takes a dangerous turn, Diggle is forced to make a difficult decision."

Suicide Squad will air on March 19 at 8 p.m. on the CW.
