Oliver must tackle a new threat to the city when bombs start to go off in Starling City. Felicity discovers the person setting them off is Mark Sheffer, a man who goes by the nickname Shrapnel. Arrow discovers Shrapnel’s next target is Sebastian Blood’s “Unity Rally” and tries to talk the alderman out of hosting it, but he refuses. Arrow sets off to stop the bombing, but Shrapnel tricks him and traps him in a bomb-laced antique store where he is unable to move without setting off the device. While Felicity helps Oliver, Diggle races to the plaza to find the bomb before it goes off. Meanwhile, Roy continues to hide his new strength from Thea but, after she witnesses his super strength in action at the rally, she demands answers. Laurels suspicions about Sebastian grow stronger once she learns that he grew up with Cyrus Gold, the man who killed Lance’s partner. After Donner refuses to help her investigate, she turns to Arrow for help. false 2014-09-14 22:19:51 Rob Hardy Jake Coburn Keto Shimizu Jake Coburn Keto Shimizu 7.6 2012 TV-14 42 The CW /config/data/metadata/library/03/03e8a4a919b37f03e7ef5bf70a1eaac0/poster.jpg Manu Bennett Actor 0 Stephen Amell Oliver Queen Actor 0 /config/data/metadata/People/S/Stephen Amell/folder.jpg Emily Bett Rickards Felicity Smoak Actor 1 /config/data/metadata/People/E/Emily Bett Rickards/folder.jpg David Ramsey John Diggle Actor 2 /config/data/metadata/People/D/David Ramsey/folder.jpg John Barrowman Malcolm Merlyn Actor 3 /config/data/metadata/People/J/John Barrowman/folder.jpg Colton Haynes Roy Harper Actor 4 /config/data/metadata/People/C/Colton Haynes/folder.jpg Paul Blackthorne Detective Quentin Lance Actor 5 /config/data/metadata/People/P/Paul Blackthorne/folder.jpg Willa Holland Thea Queen Actor 6 Katie Cassidy Laurel Lance Actor 7 /config/data/metadata/People/K/Katie Cassidy/folder.jpg Susanna Thompson Moira Queen Actor 8 /config/data/metadata/People/S/Susanna Thompson/folder.jpg Kevin Alejandro Sebastian Blood Actor 9 /config/data/metadata/People/K/Kevin Alejandro/folder.jpg Summer Glau Isabel Rochev Actor 10 Dylan Neal Dr. Anthony Ivo Actor 12 /config/data/metadata/People/D/Dylan Neal/folder.jpg Celina Jade Shado Actor 13 /config/data/metadata/People/C/Celina Jade/folder.jpg Caity Lotz Sara Lance Actor 14 /config/data/metadata/People/C/Caity Lotz/folder.jpg Byron Mann Yao Fei Actor 15 /config/data/metadata/People/B/Byron Mann/folder.jpg Colin Salmon Walter Steele Actor 16 /config/data/metadata/People/C/Colin Salmon/folder.jpg Colin Donnell Tommy Merlyn Actor 17 /config/data/metadata/People/C/Colin Donnell/folder.jpg Katrina Law Nyssa al Ghul Actor 36 /config/data/metadata/People/K/Katrina Law/folder.jpg seriesHd4tb 10 2 2014-01-15 subrip subrip 0 0 progressive False False 0.000000 0 4694375 http://thetvdb.com/banners/episodes/257655/4694375.jpg
