Deathstroke's son is coming to Arrow and Liam Hall has been cast in the role of Joe Wilson. Slade Wilson has been a vital part of Arrow over the previous five seasons, but it was most recently in season 5 that Manu Bennett made his triumphant return. After missing the entirety of season 4 and only appearing in one episode in season 3, Deathstroke came back in a big way at the end of season 5. He was freed from Lian Yu and became part of Oliver Queen's team to take down Adrian Chase.
However, the season finale left the fate of Deathstroke and nearly everyone from the cast up in the air. Thanks to interviews and other forms of confirmation, we know who will be returning in season 6 in some capacity, and that includes Slade. He won't just be returning in a small role either, as his son is now set to appear.
EW revealed that Liam Hall has been cast as Deathstroke's son, Joe Wilson. He is set to appear in the two-part Deathstroke focused episode that were previously announced, but what his future holds beyond those episodes is not known. EW also shared some character details for him, stating that he also joined A.S.I.S. and is now stuck in a Kasnian prison under the alias Kane Wolfman.
Hall has not yet had a truly breakout role, but has appeared in Lucifer, Camp, Once Upon a Time, and Before I Fall. But, depending on the recurring nature of this role, playing Joe Wilson aka Jericho could be just that. Joe Wilson is a former member of the Teen Titans, but the mute hero wound up going insane thanks to using his mind controlling powers.
How much of his comic history comes into play is unknown, but should he recur after the flashback Deathstroke episodes, there is a fair chance some of this is addressed. The potential for him to return may have already been indicated by Oliver promising to give Deathstroke information on his son in exchange for the role he played in attempting to stop Chase. If Oliver already knows about Slade's son, then he could seek him out should Deathstroke in fact be dead. Plus, maybe Joe will deem Oliver responsible for the death of his father and figure into a larger role moving forward in season 6. Whether or not that happens remains to be seen, and could largely depend on how his debut is received in this two-episode arc.
Season 6 of Arrow premieres Thursday, October 12, on The CW.
