Looks like the biggest bad on "Arrow" is officially returning to the fold.

The last time we saw Slade Wilson (Manu Bennett), he was imprisoned in an A.R.G.U.S. supermax prison on the island of Lian Yu, swearing to Oliver Queen (Stephen Amell) that he would one day escape. We at MTV News cannot confirm whether or not the man known as Deathstroke will make good on that promise, but we can exclusively reveal that Bennett will return to the show for episode #314.

So, what might that mean? Will they show some new footage of Wilson in flashback format, maybe revealing a Hong Kong connection we never knew about? Will Oliver visit him in prison for advice on taking down a different baddie, "Silence of the Lambs" style? Or will he actually escape, and return to wreak havoc on Starling City?

We probably won't know for quite some time, but either way, get ready for a whole lot more Deathstroke when "Arrow" returns in 2015. (And in the meantime, let's just bask in the glory that is the crossover episode happening this week.)
