The CW Television Network has released an extended trailer for next Wednesday's episode of Arrow: "Restoration."
The growing tension between Oliver (Stephen Amell) and Diggle (David Ramsey) puts both their lives at risk when they go after Damien Darhk (guest star Neal McDonough) and a H.I.V.E. deployed meta-human. Meanwhile, Laurel (Katie Cassidy) talks Thea (Willa Holland) into returning to Nanda Parbat to ask her father (John Barrowman) to put Sara (guest star Caity Lotz) into the Lazarus Pit. However, Laurel is surprised when Nyssa (guest star Katrina Law) refuses to do it.
