Manu Bennett is that you?
Filming is currently underway for the 100th episode of Arrow and all week long, actor Stephen Amell has teased the appearance of a mystery actor that had the fandom speculating for hours on end. Just moments ago, Amell may have Tweeted the identity of the mystery actor as he release the pic of himself and Deathstroke on a bench. With Amell wearing the same clothes he had on in an earlier social media post with fellow Arrow star David Ramsey, it seems fairly safe to assume that Slade Wilson will also be appearing in the 100th episode.
The question now is whether that's actually Manu beneath the mask? Last season, Legends of Tomorrow aired a time-traveling episode set in the future of Star City that featured an older Green Arrow taking on a version of Deathstroke that turned out to be his son, Grant Wilson who DC Comics fans will recognize as the first Ravager.
