The pair added that Arsenal is expected to be called back to the vigilante hero squad to help "resolve an urgent matter with high stakes for the team" and that he will experience "something surprising when he reunites with Thea (Willa Holland) and sparks a change in both of their lives that will have long-lasting consequences."
Haynes wrote on social media that he is "so excited to be back with the Arrow fam."
