So we now know who’s in the grave on “Arrow.” Saying goodbye to Laurel (Katie Cassidy) is sad and it’s a death fans will be reeling from for some time. There’s one very important question, though. Did Oliver (Stephen Amell) kill her?Now hold on before you jump to conclusions. We all know Damien Darhk (Neal McDonough) is the one that stabbed Laurel with Oliver’s arrow, but that didn’t necessarily kill her, did it?After all, she survived surgery and seemed to be coherent and talking after the fact, even laying her heart on the line for Oliver. Then she asked him to make her a promise. The next thing you know, Laurel is coding and winds up dead, while Oliver is confused about what just happened.While it may seem like that, the answer is no. executive producer Marc Guggenheim says, "The joke I've been making is 'Oliver Queen killed her!' But no, that was not -- there are certain coins of the realm on our show. Death is one of them, mysteries and secrets are another."
