Amell certainly thought Arrow had lost something without Manu Bennett, but what brings Deathstroke and/or Slade Wilson back to present-day?
Bennett hasn’t appeared on Arrow since a one-off, un-costumed return in Season 3, though a non-speaking Deathstroke appeared as recently as the 100th episode.
The Arrow star welcomed Bennett back over Twitter, albeit without any indication of what brings Slade Wilson back to the fold.
Far and away, Arrow’s must curious case has been the absence of Manu Bennett’s Deathstroke; often considered the series’ greatest villain.
