The Saturdays return to their still demolished headquarters (they never rebuilt after Fisk's robots made the divining rod) to retrieve tomes from Drew's library and are ambushed by Tsul 'Kalu, a cryptid whose hand now resides at the end of Zak's Claw. Doyle and Van Rook find Abby Grey while digging up info on Argost. Though out the episode, every time Zak tries to use his powers on Tsul 'Kalu, both of them have five visions.
In Zak's first vision, they saw Fisk and Komodo growling and their eyes glowing (in the same way as Zak's power) as well as ruins of buildings on fire.
In the second, they saw a crashed airplane.
In the third, a giant elephant-bug like creature and the Nagas pursue humans. A blue Naga was shown swimming in water and asked him: "What's your next command, my Master Kur?" and seemingly struck Zak with his tail.
In the fourth, the cryptids hunted down a human who asked Zak/Kur why was he doing this, to which he replied, "Because you're human." Then he orders the cryptids to attack the man.
In the last vision, they saw fire then Zak/Kur running toward a mirror and saw his future self in the mirror, as he breaks it.
At the end of the episode, Zak, believing that even the good cryptids believe him to be evil, gives up and gives Tsul 'Kalu the Claw. However, Tsul 'Kalu returns it, bows, then leaves, accepting the fact that Zak was truly good inside despite being Kur. The rest of the family appear moments after Tsul 'Kalu has departed. Doc asks Zak if he won the claw from Tsul 'Kalu. Zak replies by saying: "I think I won an ally."
