Slade Wilson or better known as Deathstroke (Manu Bennet) is set to be back in The CW series "Arrow" season 6 episode 5, titled "Deathstroke Returns."

In the previous episode, titled "Reversal," Oliver (Stephen Amell) told Felicity (Emily Bett Rickards) that Slade is asking for his help to find his son, Joe (guest star William Franklyn-Miller). The world's greatest assassin and former ASIS agent has been looking for his lost son after making amends with the Green Arrow himself fully.

According to "Arrow" season 6 episode 5's official synopsis obtained by Collider, Joe has been kidnapped by a private army. As Oliver and Slade go on their quest to find him, things will start to be pretty complicated when Slade encounters a big revelation that would shatter his hope to be reunited with his son in "Arrow" season 6 episode 5.

Meanwhile, there might be another familiar face coming in "Deathstroke Returns." It has been said that another vigilante is set to appear in Star City. However, this vigilant man is said to be wearing a mask to hide his/her identity.

Meanwhile, "Arrow" season 6's previous episode "Reversal" focused mostly on Oliver and Felicity's relationship. Fans think that seeing Olicity together in a scene does not help to improve the show's storyline that much, but episode 4 proved this claim is not true.

The superhero television series' writers have perfectly worked with Oliver and Felicity's tale in "Reversal" without dominating the entire episode's storyline. They, too, did not become melodramatic this time. Although episode 4 was basically about the couple exploring their new dynamic and Oliver being out of the team, it also delved into Felicity's well-being. This chapter showed how she managed to adapt everything that has been happening in her life.

"Arrow" season 6 episode 5 "Deathstroke Returns" will be released on Thursday, Nov. 9, at 9 p.m. EST on The CW.
