The Capillary Towel is a useful, plothole-driven tool used by assassins. A small, dark red towel, it absorbs and sends into a plothole all blood it comes into contact with, and therefore can be used to clean up after messy assassination methods, though it takes at least a few seconds to soak up what it touches. The only known example is currently in the possession of Agent Sedri, and may have limited sentience.
