At the end of last year's season finale of Arrow, Oliver Queen traveled to his home island of Lian Yu to save his friends and family. To help in his endeavor, he asked for aid from from his best friend turned sworn enemy, Slade Wilson, aka Deathstroke. In return for his help, Oliver agreed to help Slade find his long lost son.

In the months between the two seasons, the two men have been...busy, to say the least, what with that whole exploding island and secret identity outing and all. But now, Slade is coming to collect on his favor with the goal of bringing the Wilson family back together.

As the trailer for next week's episode shows, the appropriately titled "Deathstroke Returns" will bring our favorite one-eyed killer back for some child-hunting action. And not having seen his son in years, he's understandably going to be very determined to find him. Good thing Oliver's there to be a calming influence and keep a handle on things...right?

Airing Thursday nights on the CW, Arrow stars Stephen Amell, David Ramsey, Willa Holland, Manu Bennett, Colton Haynes, Echo Kellum, Rick Gonzalez, Julia Harkavy, Katie Cassidy, and Paul Blackthorne.
