Katie Cassidy is back on Arrow as Black Siren and while her return is far from ideal given her new character's evil plans, there might be some part of Laurel Lance that is hiding within her that can possibly help her be redeemed. Arrow season 6 is treading new territory with the wrap-up of its five-year story arc about Oliver Queen's (Stephen Amell) lost years after the shipwreck. With possible new storylines, fans wonder if remnants of the past will still carry on to moving forward. A familiar face like Cassidy's is a good starting point, but given her current stint as a villain, it is uncertain if she will ever be part of the good guys club again.
That said, people from Earth-1 may still give the Earth-2 doppelgänger some benefit of the doubt - hoping that she could somehow find even just a little piece of their Laurel in Black Siren. Unfortunately, it seems like there are no plans of her switching sides, at least not yet.
Arrow co-showrunner Wendy Mericle told TV Line of the possible character arc that we could expect from Black Siren - whether, at some point, a small part of her Earth-1 doppelgänger will emerge or not.
"I don't know if there's any question about whether or not the [idea] of redemption will come up; it has to. Her father is there. Oliver is there. Everyone is going to be asking whether or not it's possible to find a little piece of Laurel, the Laurel Lance they knew and loved, in there somewhere."
While it can be expected that Team Arrow will somehow try to cajole her to join them, some fans are liking this version of Cassidy in the show more. Black Siren is an interesting villain - with her history and what she represents in the show. It is also great to play off the dynamic of the heroes fighting someone who they ultimately believe can be vindicated, rather than focusing on wholly evil antagonists.
Arrow is starting a new path with season 6. The wrap-up of Oliver's Lian Yu years is almost here with just one remaining question waiting to be answered when the series returns - what exactly happened on the island right before and after it exploded in front of Oliver's very eyes. Amell has previously said that fans will find out in the upcoming season 6 premiere episode, but after that, the traditional flashbacks will be used sparingly.
The CW series is set to debut its sixth outing with the episode titled "Fallout" and filming is currently ongoing. However, production is presumably going to be halted as the cast and pivotal crew from Arrow is scheduled to descend on San Diego next week to attend this year's Comic-Con International where more morsels of information are expected to be revealed.
Arrow season 6 premieres Thursday, October 12 at 9pm on The CW.
