Role in the film
After Rose and Finn are put in prison, they meet DJ, who happens to be a hacker. After Rose and Finn escape, DJ comes with them. Soon, after being chased by the Canto Bight guards, the two find themselves trapped on a hill, when one of the guards space ships comes up behind them. They discover that it was piloted by DJ, and he helps them get away.
Later, when Finn and Rose attempt to get into the First Order ship to disable its light speed tracker, DJ uses his hacking skills to get them in. They disguise themselves as First Order officers to get inside and disable the tracker, but are captured by Captain Phasma and BB-9E. After being captured, DJ saves his own skin by buying his freedom with information on the Resistance he overheard during their travels. This information proves useful to the First Order and he is awarded his freedom, money and a ship to escape with. Phasma and the First Order Stormtroopers hand over the money to him, then give him a ship, and he flies away with the money. Nonetheless, he wishes Finn and Rose the best and reassures them that he is not loyal to the First Order before departing.
