Arrow's 100th Episode Will Feature Katie Cassidy

Oliver Queen's father won't be the only character seemingly returning from the grave for "Arrow's" milestone 100th episode. Actress Katie Cassidy has confirmed she'll also appear in the episode, which is part of the crossover event with "The Flash," "DC's Legends of Tomorrow and "Supergirl."

Cassidy shared an image on her Facebook page that depicts her name, the "Arrow" logo, and the number 100. She also added "100 #arrow" to her status update.

Her character Laurel Lance, aka Black Canary, was killed off last season, only for Cassidy to sign a deal in July to appear as a series regular across all of the network's DC Comics-based dramas. John Barrowman and Wentworth Miller made similar agreements. This allows the producers to pick and choose when and where they would like Black Canary to appear next, not unlike in comic books, where a hero can guest star in any number of titles.

At the time her new contract was announced, it was also revealed Cassidy will appear in "Arrow's" Season Five premiere. The 100th episode will air in December.

Starring Stephen Amell, Emily Bett Rickards, Willa Holland, David Ramsey and Echo Kellum, "Arrow" kicks off its fifth season Oct. 5 at 8 p.m. ET/PT on The CW.
