SUIT UP - Arsenal (Colton Haynes) and Diggle (David Ramsey) confront Laurel (Katie Cassidy) about trying to step into her sister's shoes and warn her to stop before she gets herself killed. However, when Brick (guest star Vinnie Jones) kidnaps the city's Aldermen and threatens to kill them all unless the police evacuate The Glades, it's all suits on deck. Meanwhile, Ray (Brandon Routh) steps in to help Lance (Paul Blackthorne) and the police force fight Brick, showing Felicity (Emily Bett Rickards) a new side of her boss. Malcom (John Barrowman) tells Thea (Willa Holland) that Ra's al Ghul (Matt Nable) is after him and his family and they must leave town immediately. Nick Copus directed the episode written by Wendy Mericle & Ben Sokolowski (#311).
