We have now seen the first Canary (Sara Lance, played by Caity Lotz) who became the Legends’ White Canary, the Black Canary (Laurel Lance), a second impostor Black Canary (Evelyn Sharp, who later became Artemis), and the Black Canary doppelganger Black Siren.
Instead, as we can see this new Laurel using the canary cry naturally, it’s likely that this is actually Earth-2’s Black Siren.
that the Laurel Lance who returned in the midseason finale is not the original, Earth-1 Laurel.
The news that there will always be a Black Canary in the Arrow-verse is fantastic for comic fans who feel that the Green Arrow should end up with the same character as he does in the books.
