- "In close-quarter fighting, Billaba's emphasis was always on Form III, which you favor to a ridiculous degree."
- ―The Grand Inquisitor, to Kanan Jarrus
Proficient in its use, Jedi Master Depa Billaba taught her students, including Caleb Dume—who changed his name to Kanan Jarrus after Order 66—to use Form III during close-quarter fighting. Jarrus later used Form III against the Grand Inquisitor, who recognized it as a staple of Billaba's instruction and was able to counter Jarrus' attempts to use it against him.
