The subplot in both seasons of "Shadow and Bone" is following a crew of criminals, the Crows, as they pull off increasingly impossible jobs.
The team is made up of Kaz Brekker (Freddy Carter), sharpshooter Jesper Fahey (Kit Young), spy Inej (Suman), demolitions expert Wylan (Jack Wolfe), and Grisha Nina Zenik (Danielle Galligan).
In season one, we see the Crows attempt to cross the Fold and kidnap Alina. In season two, they return home and have to fight for their lives against a powerful crime boss, before going to Shu Han to retrieve a mythical sword from a powerful Grisha saint. Finally, they are the last-minute reinforcements that help stop Kirigan and his army.
At the end of the season, Kaz gives Inej information about the slavers who took her from her parents and she leaves the group to pursue the slavers.
In the final moments of the season, Kaz comes to the team with a new mission. An addictive drug has been created called Jurda Parem that can incredibly amplify the powers of Grisha. According to Kaz, the chemist has been captured by the country of Fjerda, and they are currently trying to get the formula out of him.
Book fans will know that this is the main premise of the first Crows book, "Six of Crows," and know the band of rogues have a tough but vital mission ahead of them.
According to the "Shadow and Bone" showrunner Eric Heisserer, the "Six of Crows" storyline will be part of a spinoff series, but it has not been greenlit yet.
He told Entertainment Weekly that the script for the spinoff has been written and will be set at the same time as the season two finale.
"[It] would be its own little season of fun that our characters would get to be a part of," Heisserer said. "But of course, it's about how well season 2 numbers do. And if so, then Daegan and I will continue to carry the mantle of both shows, which is also helpful because we have a lot of mouths to feed."
