‘Arrow’ Season 4 Spoilers: Katie Cassidy tweets separation anxiety, Black Canary to be re-explored

“Arrow” Season 4, Episode 19 (“Canary Cry”) will explore the notion that Black Canary is a mantle that could fit someone else. Meanwhile, Katie Cassidy has gone on Twitter to give Emily Bett Rickards a shout-out and confess to “having serious withdrawals.”

Spoiler alert: This update contains “Arrow” Season 4 spoilers. Details include the plot developments in the recently aired episodes. There is no new episode of “Arrow” this week on The CW; Episode 19 will air on April 27.

Before the character in the grave was revealed to be Cassidy’s Laurel Lance in Episode 18 (“Eleven-Fifty-Nine”), Cassidy had said in an interview that the dying character would be “taking one for the team.”

While her media interviews showed Cassidy met the change with a positive outlook, the actress is not above confessing that she misses her co-stars, particularly the actress playing Felicity Smoak, Emily Bett Rickards. See her tweet below.

Cassidy’s fans have not seen the last of Laurel Lance. Her death in “Arrow” Season 4 is for real; show boss Marc Guggenheim even said Paul Blackthorne’s Quentin Lance will be heading over to “DC’s Legends of Tomorrow” to break the news to White Canary, Sara Lance (Caity Lotz). However, Laurel could still appear in “Legends” in one of its time-travelling escapades.

It has also been revealed that Katie Cassidy will guest star in an upcoming episode of “The Flash,” another sister series to “Arrow.” Barry Allen (Grant Gustin) and his team will encounter Black Siren, the doppelganger of Black Canary in Earth-2.

Will there be a new Black Canary? Guggenheim indirectly answered this question but said viewers will see “Arrow” exploring the notion that Black Canary’s cry could be heard from someone else.

“I think [Black Canary is] a mantle that multiple people have had. We’ll play with that notion in Episode 19. I personally like the idea that DC Comics, all the comics, they all have the concept of legacy. We’ve seen on Legends that someone picks up Oliver Queen’s mantle, for example,” Guggenheim told Entertainment Weekly.
