If you tuned in for Arrow Season 7 Episode 18, titled "Lost Canary" on Monday night, there's a good chance you thought The CW drama was losing another series regular ahead of its final season.

The explosive installment focused on Laurel returning to her old ways as Black Siren. It even resulted in Sara Lance returning to help the Earth-2 iteration of her sister see the light.

In the end, Laurel returned to the side of good, but there was a major caveat:

Laurel decided that the best course of action for her was to return home to Earth-2 with the aim of tying up loose ends and making a life for herself on her home planet.

The plot twist left many fans reeling, primarily because it seemed to confirm that Katie Cassidy's tenure on the series was over.

Thankfully, that's not the case.

Speaking to TV Line after "Lost Canary" aired, Arrow executive producer and showrunner Beth Schwartz confirmed that fans have not seen the last of Laurel.

“Katie does not leave the show; she comes back this season … It appears like [she leaves], but it’s not true," she teased, adding:

"She’s still [part of the show].”

That's a good thing, especially when you consider the series has lost a series regular already during Arrow Season 7 and will be losing another at the end of the season.

Echo Kellum departed the series earlier this year, leaving behind his Curtis Holt role, but there's word that he could pop back up as a recurring player.

Then there's Emily Bett Rickards, who has played Felicity Smoak since Arrow Season 1. Rickards confirmed last month that she was bowing out of Arrow ahead of its final season.
