The episode appears pretty epic in scope, with Team Arrow and others -- police? Regular citizens? -- squaring off against Brick and his street gang in the Glades. And, from what we can tell, Oliver returns and makes a rather grand entrance.
You can check it out below.
Still operating without Oliver (Stephen Amell) and desperate to stop Brick (guest star Vinnie Jones), Team Arrow is forced to consider Malcolm's (John Barrowman) offer to help shut Brick down as Malcolm has a personal score to settle with the felon. Roy (Colton Haynes) and Laurel (Katie Cassidy) point out that the team could use some help to save the innocents of The Glades, but Felicity (Emily Bett Rickards) is adamantly against it. They look to Diggle to make the final decision. Meanwhile, the flashbacks chronicle Malcolm's descent from kind-hearted father and husband to cold-blooded killer after the murder of his wife.
Arrow airs Wednesday nights at 8 p.m. ET/PT on The CW.
