The return of Laurel Lance will raise some obvious questions (and a few eyebrows) among Star City’s citizens if Black Siren’s presence on Green Arrow’s home turf becomes public.
Everyone now knows that Laurel was Black Canary, and everyone also knows that she died at the hands of Damien Darhk back in 2016.
As a result of “Laurel’s” unexpected return (not to mention the continued presence of Harry Wells in Central City), the truth of the multiverse could soon bubble to the surface.
That said, as she becomes a more prominent villainess in the Earth-1 landscape, people are soon going to notice that the famous (and very dead) lawyer turned vigilante has started running around the city committing crimes.
