User blog comment:Eobard95/Arrow premiere ending - Who saved Black Siren?/@comment-1183010-20171014104350

I think it could be Richard Dragon personally. I think that Black Siren's fighting abilities have increased over the five months, it seems that she and Dinah were about even on Lian Yu but in 6x01, she ran circles around Dinah. I think since Dragon is going to be Green Arrow's villian, he would have trained Black Siren to the point that she could even put up a fight with even Oliver. We will have to see if they have a Green Arrow/Black Siren fight and see if this is true.

I think Cayden James might be involved but I see him being more of a villian for Felicty & Curtis, I think he and Black Siren are working together as I think he wanted the prototype T-Sphere so he can understand it and allow them to fight them and even hack Cirtis's T-Sphere.
