Between trips to Central City and dealing with overly-devoted fans, season 3 of Arrow has largely focused on the death of a major player as well as the subsequent mystery of who killed said character. Previous seasons of the CW’s superhero drama revolved around certain villains: the Dark Archer in season 1, Deathstroke in season 2, and season 3 will see the introduction of Ra’s al Ghul. While the Dark Archer has already returned to Starling City, Slade Wilson a.k.a. Deathstroke (Manu Bennett) has been missing from the series since his defeat in last season’s finale.
Deathstroke’s absence is, of course, the result of Oliver Queen (Stephen Amell) locking up the villain in an ARGUS supermax prison on the island of Lian Yu. Although it’s unclear if Deathstroke will make good on his threat to escape the prison, it has been confirmed that Bennett kept his promise of returning to Arrow.
MTV is reporting that Bennett will reprise his role as Wilson/Deathstroke and appear in episode 14, after the show’s midseason break. However, it wasn’t specified whether Wilson will be featured in Arrow’s present-day storyline or flashbacks of the show.
In the season 2 finale, Wilson promised Oliver he would escape from the ARGUS prison - despite having been cured of his Mirakuru-fueled strength. But that may not necessarily be the manner by which Wilson returns to Arrow. He could appear in flashbacks or Oliver could visit the villain on Lian Yu. Or, since Arrow has already established a group of criminal operatives under Amanda Waller’s command (the Suicide Squad), Wilson could return as a part of the ARGUS team.
Since Arrow’s season 2 episode “Suicide Squad” was announced, rumors of a spinoff have circulated. The president of the The CW even added fuel to the fire when he said more spinoffs - in addition to The Flash - are being “discussed.” Should Wilson return to Arrow as a part of the Suicide Squad, it may add more credence to the possibility of the team getting its own series.
However, Warner Bros. and DC are currently developing their own big screen incarnation of the Suicide Squad along with some A-list talent. Although that doesn’t necessarily mean The CW wouldn't consider a series based on the team, especially since Arrow has already done the groundwork, it does complicate things.
That being said, it’s still unclear in what fashion Bennett will return to Arrow in episode 14. He may still be locked in the ARGUS prison on Lian Yu without a clue as to Waller’s team of operatives, or he may return in another capacity.
Arrow continues on December 3rd with “The Brave and the Bold” @8PM on The CW.
