The CW already seemingly spoiled the explanation behind Arrow returning one of its biggest characters in midseason finale “What You Leave Behind,” but there’s wiggle room yet. Case in point, an extended 2017 trailer for next week’s “Who Are You?” hints at a Flashpoint explanation, along with new wrinkles to the Prometheus story.

You’re warned of likely Arrow spoilers from here on out, but where the first 2017 trailer heavily implied that the resurrected Laurel was in fact the “Black Siren” of Earth-2, the extended promo for next week’s “Who Are You?” sees Oliver under the impression that time-travel is responsible for Laurel being “saved.” Prior Flashpoint changes have overwritten memories of the past, making it unlikely the real Laurel somehow survived Damien Darhk, but it’s always possible there’s a grander sci-fi explanation at work here.

In any case, so reads the “Who Are You?” synopsis:

OLIVER WANTS JUSTICE; FELICITY WANTS REVENGE — Worried that Prometheus is right and he is truly a killer at heart, Oliver (Stephen Amell) looks for any ray of hope and finds it in what seems to be the miraculous return of Laurel Lance (guest star Katie Cassidy).

However, Felicity (Emily Bett Rickards), still reeling from Detective Malone’s murder, is bent on revenge – she wants to stop Prometheus at any cost. While in prison, Diggle (David Ramsey) fights for his life.

Producers have also implied that Arrow will “always” have a Black Canary in some form, but what might the larger endgame behind Laurel’s return be? Could she be participating in one of Prometheus’ mind-games? Stay tuned for the full premiere next week to find out.
