Summary
Analysis
Wylan disables the winch before any guards arrive, to Jesper’s surprise. They see guards as they leave the gatehouse—but the guards are focused on two Shu Tidemaker Grisha, who are clearly on jurda parem. They drain the guards’ blood and then notice Jesper and Wylan. As they start to drain Jesper and Wylan’s blood, Wylan tells Jesper to fabrikate. Jesper concentrates on all the bits of metal on his clothing, and he sends the shavings flying at the Grisha. He drives it into their bodies, which disables them. Jesper feels sick as he leaves them screaming—he may have killed “two of his kind,” and suddenly, that seems to matter.
Jesper is beginning to accept his identity as a Grisha. He not only calls on his power to save himself and Wylan—something he’s barely able to do, because he's had no practice—but he also feels remorse at the fact that he killed two Grisha, who are in many respects just like him. In particular, using “two of his kind” to refer to the Grisha suggests that Jesper identifies more now with Grisha than he ever has before.
