After that cliffhanger of an ending the mid-season finale of the series presented just before the show went on holiday break, The CW (via Television Promos) has released a brand new extended promo for the 10th Episode of Season 5 of "Arrow", whose episode title is "Who Are You?" and shows the return of a character thought dead... Or is it?
SPOILERS after the jump if you're queasy about seeing who's who, so view at your own risk.
And it looks like "Laurel Lance" is back... But those who watch "The Flash" will recognize this version is "Black Siren" - the evil Earth-2 counterpart of the Black Canary we know and love. We'll just have to wait and see how this all plays out when the show returns from hiatus on January 25th.
