As the members of the team struggle to deal with the death of Laurel (Katie Cassidy) an impulsive young woman (Madison McLaughlin) assumes the identity of Black Canary and begins targeting those she blames for the death of her parents. Whether or not she stays dead, or is eventually resurrected like so many of the characters in the series so far, “Canary Cry” certainly attempts to sell the idea that Laurel isn’t coming back (even going so far as to publicly out her as the real Black Canary at her funeral). Cassidy does appear in the episode as we get flashbacks of Oliver (Stephen Amell) and Laurel following Tommy’s death rather than scenes from the island this week.
Barry (Grant Gustin) struggles to readjust to life without his speed which proves even more difficult when Harrison Wells (Tom Cavanagh) is kidnapped by a meta-human (Haig Sutherland) while searching for Jesse (Violett Beane). Even without his powers, Barry can’t sit back and do nothing. Gathering the team and Jesse together for a little old fashioned police work, and a bit of luck, the Flash races into action (albeit at a much more normal pace).
With the threat of LOCKSAT once again looming in the background, Castle goes for goofy in the attempted murder of a safety inspector (Jonathan Silverman) who survives poisoning, electrocution, and being shot in the head. With Castle (Nathan Fillion) consumed by the man’s incredible survival, something the writer attributes to super-powers, Beckett (Stana Katic), Ryan (Seamus Dever), and Esposito (Jon Huertas) are more concerned with finding the would-be killer.
When Watson‘s (Lucy Liu) inside man turns up dead Morland Holmes (John Noble) becomes Sherlock Holmes‘ (Jonny Lee Miller) prime suspect. After fuming at Watson for keeping such a dangerous secret from him for weeks, Sherlock jumps into the case and, despite what he may wish to be true, quickly proves his father wasn’t behind the hiring of an amateur hitman (Yul Vazquez). The truth, however, will shock him as the show teases the possible return of a fan-favorite character in the season’s remaining two episodes.
The relationship between estranged siblings is the theme that runs through both storylines in Once Upon a Time. The main story returns Cora (Barbara Hershey) as Regina (Lana Parrilla) enlists her mother’s help to try and prevent Zelena (Rebecca Mader) from accepting Hades‘ (Greg Germann) offer. During the flashbacks of the episode we learn that the two sisters met once, well before their first run-in in Storybrooke. It’s this revelation, and not Cora’s sinister plan to wipe her daughter’s memory, that eventually allows the sisters to call a truce. Despite her misgivings, Regina is now willing to trust her sister, but it appears Rumpelstiltskin (Robert Carlyle) and Peter Pan (Robbie Kay) have other plans.
Adam‘s (Ian Anthony Dale) prison stay gets a bit more interesting with news of Gabriel Waincroft‘s (Christopher Sean) visit to the prison reaches not only Five-0 but also the new head (Michelle Krusiec) of the Yakuza in Hawaii who goes to great lengths to makes sure Adam turns up dead before working for her competition. When arranging a situation where the prison would have to evacuated and then hitting the bus Adam is on with an IED doesn’t end up killing the target, Yakuza hitmen are sent into the jungle after Adam and five other fleeing convicts.
When various members of the team are targeted by the Time Lords‘ assassin the Pilgrim (Faye Kingslee), Rip Hunter (Arthur Darvill) leads his motley crew through time to protect their younger versions before the assassin can wipe them out of existence. When her plan is foiled (thanks to a convenient plot device that allows the assassin only to target each member a single time in their timelines), the Pilgrim decides to use the team’s loved ones as hostages to force a confrontation. Of course it helps that the crew know exactly where in time and space the assassin plans to attack (based on some hazily-defined probability equations made by the ship’s computer in another convenient plot device).
In an episode that begins with a flashback to Earth-2, “Versus Zoom” gives us darker version of the origins of Barry (Grant Gustin) as we witness the tragedy of Hunter Zolomon’s childhood which would lead him down the path to taking on the personas of both Jay Garrick and Zoom (Teddy Sears). Opening with a sequence that helps explain Barry’s short stint on Supergirl, the episode is mainly concerned with the Flash and his friends setting another trap for Zoom which, to absolutely no one’s surprise, goes wrong.
The recent news that Stana Katic will be leaving the show at the end of the season means should Castle be renewed for another year it’s likely future episodes will look more like “Backstabber” in which Hayley (Toks Olagundoye) gets herself into a jam and relies on the help of Castle (Nathan Fillion), Alexis (Molly C. Quinn), and their friends at the NYPD. After being used by a former friend and colleague for a less-than-legal break-in, Hayley finds herself in the middle of a murder as her past as a spy catches up with her.
