'Arrow' Season 4 Spoilers: Twitter Reacts Stephen Amell/Oliver Queen Grave Mystery Twist!

The CW Network finally revealed the person inside the grave mystery on Season 4 of Arrow. Twitter had lots to say as Oliver Queen aka The Green Arrow (Stephen Amell) discovered the shocking twist behind the death at 11:59.

In our previous recap, after seeing his boss in trouble, Curtis (Echo Kellum) joined Oliver in helping rescuing Felicity from the Bug-Eyed Bandit (Emily Kinney). Even after being scolded by the Green Arrow, Curtis refused to back down and helped the team fight off their opponent. As Damien plans his escape from custody, Malcolm (John Barrowman) sends a message out to Diggle's brother, Andy.

In our recent recap, Diggle and the Green Arrow were betrayed by Andy as Damien Dhark (Neal McDonough) set up the prison riot. Using his mystery powers, Damien forced the Green Arrow to watch as he stabbed Laurel Lance aka Black Canary (Katie Cassidy) to death. Laurel proclaimed her love for Oliver before she passed away, leaving her father, Captain Lance (Paul Blackthorne) truly alone.

In an interview with TV Line, Cassidy discusses her death scene, "That scene when I'm in the hospital and I say goodbye [and] I say to the team, 'I never wanted this. I was thinking of giving up the Black Canary. I can do it,' it was so real shooting it because it was my saying goodbye to the team and all of us. So it definitely wasn't difficult for me to get to that emotional point."
