"Arrow" season 3 returns on The CW with some new challenges for Oliver Queen (Stephen Amell) and Thea Queen (Willa Holland) in episode 14.

Malcolm Merlyn (John Barrowman) will send the Queen siblings to Lian Yu for preparing themselves before "The Return" of Ra's al Ghul (Matthew Nable). But the two will ultimately land up in a dangerous situation with Slade Wilson aka Deathstroke (Manu Bennett).

The evil character wants to use Queens as a means to escape from the underground bunker, where he has been imprisoned.

Although he will use all his power against Oliver and Thea, the siblings will manage to save themselves from the hands of Deathstroke.

However, showrunner Andrew Kreisberg indicated that they are still in danger. In an interview with  TV Line, he said, "When he comes back, he's out for blood".

Meanwhile, the flashback sequence of "Arrow" season 3 will show "The Return" of Oliver and Maseo Yamashiro (Karl Yune) to the Starling City and they are in a mission to retrieve the Omega bio weapon.

As per the official synopsis, Amanda Waller (Cynthia Addai-Robinson) will ask Oliver to hide his identity from everyone. But he will go in search of Tommy Merlyn (Colin Donnell) and Laurel Lance (Katie Cassidy).

The CW will air the new episode of "Arrow" season 3 titled "The Return" this Wednesday, 18 February, at 8pm. The supernatural series will be live streamed here.
