- The sword acts similarly to the Heroin (TLAD) and the Diamonds (TBoGT) in the sense that it is the plot item, and that the character has to work to get it back. The main difference is that the sword is a weapon, and that it is personal for Huang, while the Heroin and the Diamonds are business for the others.
