According to EW.com Liam Hall will join the cast of Arrow in season six as Joe Wilson, the son of Slade Wilson (Manu Bennett).
Joe Wilson will be introduced in the two episode Deathstroke story where we will see the anti-hero team-up with the Green Arrow (Stephen Amell) to rescue his son. Joe is currently in a Kasnian prison operating under the alias Kane Wolfman. We will learn that Joe has followed in his father footsteps by joining the secret Australian military agents, ASIS.
In any case, Joe Wilson is better known in the comics as Jericho. Joe is a mute but his abilities include controlling people’s bodies through eye contact. He was a longtime member of the Teen Titans, although he occasionally found himself fighting against them.
Arrow will move to Thursday nights with the sixth season premiere on October 12th.
