MTV reports that Bennett will be back for the fourteen episode, but it is not currently known in what capacity.
As noted, the last time Slade Wilson appeared, he was imprisoned in an A.R.G.U.S. supermax prison on the island of Lian Yu, swearing to Oliver Queen that he would one day escape.
Will Slade Wilson keep good on that promise? Or could the upcoming appearance be a flashback scene?
Well, we are going to have to wait until Arrow returns following the mid-season break to find out.
Arrow airs Wednesdays at 8pm ET on the CW.
