Arrow Season 4 Finale: 11 Big Questions That Need Answering
3. How Will Oliver Stop Darhk?
So far, Oliver has only been able to defeat Darhk on two occasions: once when he robbed him of his powers, and later when he gained some magic of his own.
Given he's going to have to figure out a way of defeating Darhk in the finale, that means he's got those two options in how to do it, or at least that's how it seems right now. Will he be able to fully channel the Light in order to take on Darhk and win, or is it going to come down to the aforementioned surprising force to help take Darhk down for good?
