Re-reading Tiamat’s Wrath.

In Persepolis Rising, a “bullet“ appeared on the Tempest, locked to the ship’s frame of reference, and stayed there through that book. We don’t have any pov chapters onboard the Tempest in Tiamat’s Wrath, but there’s also no mention of the bullet during any of Elvi’s chapters or any mention of it from Trejo. What happened to it?
