Arrow Season 4 will arrive in just a few days’ time, and The CW has afforded no shortage of previews and teasers for the October 7 premiere. We also know that initial episodes will help set up 2016's Legends of Tomorrow by the return of Sara Lance, and the newest press release tells us when, and how it will happen.

The CW let fly the third press release of Arrow Season 4 with October 21's “Restoration,” in which Laurel leads the charge to bring her sister Sara’s body to the Lazarus Pit in Nanda Parbat. As we observed in the trailer, Nyssa protests the decision, but … well, spinoff characters don’t resurrect themselves.

WEDNESDAY, OCTOBER 21

ARROW
“Restoration” — (8:00-9:00 p.m. ET) (TV-14, LV) (HDTV)

LAUREL TAKES HER SISTER TO NANDA PARBAT — 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.

Wendey Stanzler directed the episode written by Wendy Mericle & Speed Weed (#403). Original airdate 10/21/2015.

Granted, we don’t yet know exactly what influences Laurel to begin the resurrection process (having had awareness of a Lazarus Pit for the better part of a year), while we do know that the fifth episode of the season will see John Constantine (Matt Ryan) assisting with Sara’s return to life. It’s possible Sara herself doesn’t enter the pit until sometime after “Restoration,” but we at least have a clearer picture of why it happens.

So reads the October 7 Arrow premiere synopsis of “Green Arrow”:

MY NAME IS THE GREEN ARROW

Oliver (Stephen Amell) and Felicity’s (Emily Bett Rickards) blissful getaway is cut short when Thea (Willa Holland) and Laurel (Katie Cassidy) pay them a visit and tell Oliver they need his help back in Star City. The city has been attacked by “Ghosts,” assassins led by a dangerous man named Damien Darhk (guest star Neal McDonough). However, when Oliver returns, Diggle (David Ramsey) makes it very clear that he doesn’t want Oliver on the team.

So far, we know of Arrow Season 4 that the fourth year is expected to somewhat creatively revamp the series after its Season 3 finale saw Oliver retiring the vigilante lifestyle. In addition to a focusing on DC villains H.I.V.E. and Damien Darhk (Neal McDonough), Season 4 will also introduce Rutina Wesley, Parker Young, Jeri Ryan’s Jessica Danforth, J.R. Bourne’s Double Down, Echo Kellum’s Mr. Terrific and Alexander Calvert’s Anarky.

Apart from Wendy Mericle’s elevation to co-showrunner alongside Marc Guggenheim, we also know that Punisher: War Zone director Lexi Alexander will helm an episode, and both Oliver and Diggle will sport new looks.

Arrow Season 4 will premiere on October 7, but check out the trailers below, and stand by for the latest!
