User blog comment:Xandermcc/Deathstroke is joining Team Arrow?/@comment-26624146-20170421093923

So does that mean you agree with me about Black Siren now?

Also an Oliver and Slade team up is something I have also wanted for a long time, that and a Malcolm vs Slade fight, but I don't think he'll join Team Arrow. Most likley he'll vanish afterward to avoid capture and be more of a recuring enemy to Team Arrow, or he'll do what we've all been wishing for and "keep his promise", to the "girl with the glasses".
