SPOILERS/NSFW - DC on SCREEN #150 - Arrow 4x18 - Eleven-Fifty-Nine | Review - After months of speculation, the question is finally answered.  Damien Darhk, as if you couldn't have guessed, was the dirty deeder, and he placed one of Ollie's arrows into Larurel Lance to keep his word to Quentin.  Even worse, Darhk only had the upper hand in the fight because Andy Diggle betrayed the team (as Oliver said he would) leaving John blaming himself for Laurel's death.  It's a tough world these characters live in.  Anyway, sit back and enjoy (or re-live) our thoughts (both good and bad) on this episode of Arrow!
