Last Wednesday's "Arrow" shocker apparently left this question hanging for "Legends of Tomorrow": how will Sara Lance react when she finds out that Laurel is back?

Following last Tuesday's episode of "Legends of Tomorrow", entitled as "Raiders of the Lost Art", Sara/White Canary has been trying to get her sister, Laurel Lance/Black Canary, back as she learns about her fate in the hands of Damien Darkh (from "Arrow"), as reported by Entertainment Weekly. Apparently, Damien is now considered as the main antagonist - all thanks to him being part of the recently introduced "Legion of Doom" in the DC TV-Verse.

In the same publication, Executive Producer Marc Guggenheim has earlier mentioned that while Sara got her much-needed closure regarding Laurel's death during the "Invasion!" crossover event, she is still hopeful on getting reunited with her sister. So, how will Sara react when she finds out that Laurel is back, even if she is not what it seems to be?

In the "Arrow" midseason premiere just last Wednesday, entitled "Who Are You?", Laurel Lance (guest star, Katie Cassidy) was telling Oliver about how she was saved and mentioned seeing a "white light". She then goes on to say that it was just like what most people say - meeting an angel. The angel reached out for her, but then she realized that it wasn't an angel - it was her sister who saved her.

But just like "The Flash", whose characters are very much well and alive in other Earths, the Laurel Lance Oliver and Felicity just saw wasn't actually the one on Earth-1, but "Black Siren" of Earth-2, as further detailed on Movie Pilot. Still, Laurel returning to "Arrow" will possibly make Sara even more cautious or surprisingly accepting - just to save the memory of her sister from the impending doom that is the "Legion".

Viewers will just have to wait and see Sara's reaction when she finally meets Laurel Lance of Earth-2 on "Legends of Tomorrow".
