Aiden got Kamal a job working for Forihoff to find out how some card players were winning so much money. With Kamal's hacking skills he was able to quickly find out how the suspects were counting cards and was able to ghost their leader with an audio mask. By ghosting or talking with the someone voice he lost the all the card counters money to the casino.
Forihoff was grateful and gave Aiden and Kamal a huge payout. However, he paid in casino chips, money only good in the casino, making Kamal have to cash it out in small portions over time.
