Meanwhile, Emerson is at his office eating takeout from the dim sum restaurant when he finds a fortune cookie with a message asking him for help.

Emerson lets Chuck and Ned know what's going on, and leaves to track down some leads. Olive reports that Dwight returned again and Chuck thinks that Ned should help him. Ned finally relents and gives Chuck his father's address, for her to give to Chuck. As it turns out, Ned has had the address for 20 years, ever since he learned that his father had moved on to start a new family without him.
Bao's old friend Hua Jaing comes to the Pie Hole and informs them he overheard Emerson at the restaurant. He explains that there has been a gambling ring at the restaurant since Prohibition, and it has been going ever since. The trio goes to the restaurant and hides between a curtain to spy on Simone, who is at a table with several other men. The team concludes that the meal is actually an elaborate game using food for cards.
Emerson calls Simone to his office to question her about the gambling. She explains how the game works and offers a review of the other gamblers and how likely they are to kill Bao.

She kisses him and he responds against his better judgment.
Chuck and Olive visit Ned's father and find twins Ralston and Maurice rehearsing a magic trick. They're the teenage sons of Ned's father from his second family, and they explain that their father abandoned them too. They quickly exit while wondering what Ned would think of discovering he has two half-brothers.
After Simone leaves, Emerson goes over photos of the restaurant and spots a busboy in every photo, wearing an expensive watch. Emerson calls in Ned and Chuck, and the busboy watches them. Chuck tells Ned she went to his father's house and Ned is less than thrilled. The busboy makes a run for it and they follow him through the kitchen. Emerson spots a curtain but only finds the steamer for Bao's steamed buns behind it. It starts to rattle and explodes, firing a pipe through a shelf of jars and impaling the hiding busboy.

She reveals that Bao lost heavily trying to make money to pay for the restaurant. Shrimp Boy extended him credit in return for his promise to have Mei marry Rubbie Wu, Shrimp Boy's socially-inept cousin.
Emerson figures Shrimp Boy killed Bao and they need to talk to him after getting around his bodyguards. Emerson dismisses Simone as a suspect, leading Ned and Chuck to conclude that he and Simone got together. After Emerson leaves, Olive comes over and apologizes along with Chuck for going to Ned's father's home without telling him. Chuck insists he needs to seek out his family but Ned says that they're his family now. Ned doesn't want to reach out to his half-brothers in case it makes his father happy.

As he hides from Simone, he gets an ideaâ€¦ and sends Chuck and Olive in undercover as Chinese waitresses. They slip a drug into the tea for Shrimp Boy's bodyguard, forcing them to run to the restaurant. Olive locks them in the bathroom while Emerson and Ned arrive in disguise to enter the game.
