‘Arrow’ Season 2 Preview: Oliver and Diggle Head to Russia to “Keep Your Enemies Closer”

'Arrow' has been crushing it in its first five episodes of season 2, but will the vigilante gang have as much luck abroad, tasked with a mission to Russia? Next week's "Keep Your Enemies Closer" will see the return and debut of several DC faces as Oliver and the others head out on an international rescue mission, so take a look in the full photo set inside!

Not only will next Wednesday's all-new installment return Deadshot (Michael Rowe) to the fray, but it'll also see the debut of 'Spartacus' vet Cynthia Addai-Robbinson as DC mainstay Amanda Waller. More than that, Summer Glau will drop by once again as Isabel Rochev, insisting on joining Oliver's "business trip," while Caity Lotz returns as Sara Lance in flashback, at least.

Says The CW of next week's "Keep Your Enemies Closer":

Amanda Waller (guest star Cynthia Addai-Robinson) sends A.R.G.U.S. agents to kidnap Diggle (David Ramsey). Waller informs Diggle that Lyla (guest star Audrey Marie Anderson) has gone missing after following a lead on Deadshot (guest star Michael Rowe) in Moscow. When Diggle tells the team he’s headed to Russia to rescue Lyla, Oliver (Stephen Amell) and Felicity (Emily Bett Rickards) decide to join, but things get messy when Isabel (guest star Summer Glau) shows up on the tarmac and insists on joining Oliver’s “work trip.” Meanwhile, Moira’s (Susanna Thompson) lawyer, Jean (guest star Teryl Rothery), tells Thea (Willa Holland) that dating Roy (Colton Haynes), a known criminal, is hurting her mother’s case.
