Patrick sits down at a blackjack table and proceeds to win. He asks the dealer to change his chips in for $1000 chips. He then takes his larger value chips and heads to the high stakes table. He introduces himself to the dealer and proceeds to win. Teresa, Grace and Matt are in the security room when Matt gets a call telling him that there is possible cheating at table 43. The three head down and see Patrick's huge pile of winnings. Matt tells Patrick to leave after Patrick explains that he just memorized the cards. Patrick then tells Matt that the dealer was cheating by flashing her cards to the man at the end of the table and dealing the second card off the top to all the others.

The team returns to the headquarters. Patrick discloses that he won $250,000. Cho questions Alexandra, the dealer, about why she was cheating. She tells him that she was just trying to save up enough money to pay for a liver transplant for her mother. Cho asks if anyone else was working with her and she says no. He asks if Jim fired her because he found out she was cheating. She says yes, but maintains that she didn't kill him. She says that she found out he was dead and just acted like she was never fired. Patrick wonders why Jim didn't tell Matt. Patrick sticks his head in the interrogation room and asks if Matt was in on the cheating too. She says no and Patrick tells her she can go.

Teresa is upset that Patrick wants to release Alexandra. Patrick tells her that Matt will find out she was let go and may become nervous that she cooperated with them and told about Matt's role in the cheating. He might then be more likely to confess.

Patrick hands boxes of jewelry to Grace and Teresa. They are impressed, but say they can't accept the gifts. Patrick tells them that he won the money fairly and can spend it however he wants. Cho and Wayne ask if he got them anything. Patrick pauses, then tosses them each an expensive watch. He tells the team he wants to take them all out for a fancy dinner later. Teresa points out that it wouldn't look good if they were seen living it up, so Patrick takes them to a dive bar instead. At the bar, Patrick tells the team that he was able to memorize the cards by assigning them to living things and putting them in his memory palace which is a carnival that his dad used to take him to when he was little. The team doesn't understand his method, but he insists that it works. The ladies take off their jewelery and give it back to Patrick. They thank him, then leave. The guys ask if they can keep their watches and Patrick says of course.

That night, Patrick tosses and turns in his hotel bed. He gets up early, packs up the jewels and cash and gets dressed. He puts the bag of money into a deposit box for a Planet Aid charity. Teresa then calls him and tells him to meet her at Ann's house because she wants to confess something.
