After being lashed, Oliver's mystical tattoo lit up, causing the leader to stop Conklin. Oliver then grabs the guys gun and aims it at himself. Oliver then asks for Taiana's safety in exchange for him helping the man. Conklin however spent the whole time telling him it was a bad idea. Oliver and Taiana are then taken to prison. Conklin locks Taiana and Oliver in a cell.

Laurel learns that her dad is seeing Donna Smoak.

Machin heads to Damian's home and holds Damian's wife and daughter hostage. The Green Arrow, Speedy, Dig, and Canary show up to stop him from killing the hostages. Canary and Dig untie them as Speedy and green Arrow battle Machin. They split up and Oliver spots Damian from a distance. Instead of going after Machin, Oliver goes after Damian whilst Speedy ties up Machin. Damian uses magic to injure the green arrow and then asked after his family. Damian tells him that he could enjoy his time with his family, as a result of the green arrow saving his family. Speedy is knocked out by Machin. Afterwards in the arrow cave, they discuss what happened. Thea calls her boyfriend back to her and Laurel's place where they have red wine and kiss.
