A day with Harley and Gus where they fight crime, babysit and make an important decision that could change their lives.
Gus is at the bar purchasing a small package from a buxom drug dealer. She asks him if he'd like to see the other services she provides and he begins to escort her out when Harley stops them. Within a moment, the jig is up as Harley and Gus come clean about being cops before they arrest her. Marina and Remy show up to take her off their hands and they leave. When they get outside, they find Ashlee taking their kids home from babysitting. She begins to compliment them on how 'together' they are and says that they seem to have it all.
When they get home, they have a picnic with their two sons in the living room. Gus retells the evening exploits in comic book terms with himself cast as 'Supercop' and Harley as 'Badgewoman.' She's not impressed that he continually downplays her role, and after shooting him dirty looks, he relents and pulls out paint swatches for the living room. Gus tries to make a toast 'to family and...' but Harley keeps stopping him because she says that when things get too cliched on TV they always turn out badly. Frank interrupts dinner to assign them to another case (chasing down the husband of the woman they arrested) and they leave him with the children until Ashlee comes.
Once they leave, Harley continues to nag Gus for always making her the sidekick in the stories he tells the boys. While they wait to break down the door of the man they're after, Gus shows Harley the video feed he gets on his phone. In it, they can see Ashlee hopping around with their children. Various noises come out of the room and they start arguing about whether or not they should call for backup. Suddenly, there is a gun shot through the door followed by more noise and they continue to argue. When they finally kick in the door, they find that the man they're after has escaped. The only person left in the room is a baby girl sitting on the bed. It's the baby of the woman they arrested earlier.
Harley can't stop smiling at the baby as they take it back to the station with them. She tries to get Gus to sing to the baby with her, but he's afraid her singing will scare the baby. They start to sing anyway and he gets all the words wrong. The baby starts to cry and Frank interrupts to tell them that social services are swamped and they might not be able to get anyone over to the station that night. Gus tells Harley that the baby is hungry and she should be breastfeeding it. 'I'm not a faucet,' she says shaking her head and sending him home to look after the boys. After Gus gets the boys ready for bed, Harley arrives with the baby in tow. They all gather around and talk to the baby. She asks the boys to give it a name and, after trying some dog names, they decide on 'Gracie.' Since there is no crib, the baby sleeps with a beaming Gus and Harley.
The baby cries through the night. In the morning, Gus and Harley are disoriented and drowsy. They even send the boys to school in their pyjamas. Gus offers to stay home with the baby and deal with social services. At the station, drowsy Harley is startled by Frank trying to wake her up with more coffee. He tells her that social services are looking for them and a disappointed look crosses her face. She immediately calls Gus and asks him why he hasn't called social services yet, but he assures her that he is taking care of everything and has to go. He hangs up to change the baby, but Harley imagines something is wrong and wants to rush home to find out. Frank stops her and says that he is worried that Gus might already be too attached to the baby, but Harley says the he's wrong and, annoyed, storms off. When she arrives home, Gus tells her that the baby is already gone and is now with her grandmother. He's obviously saddened by this and glumly tells her that 'the baby has her home and you have your home back, just like you wanted' before walking out.
Harley can't believe what he just said and goes after him. She suspects there is something wrong because he never leaves without saying goodbye. Together, they go to see the baby with her grandmother before they leave town. She and Harley have a chat where she thanks her and tells her that she has quite a man in Gus. Harley asks to hold the baby one last time and tells her that she had a good time looking after her and will miss her. She returns to Gus and they're both upset. Gus tries to reassure himself by saying that a baby always belongs with its family.
Harley is unsure about Gus' recent behavior. At the station, Frank starts to tease her when she goes on about how important order and routine are to her when she is married to 'the most unpredictable man I know.' She doesn't appreciate all the teasing and goes to question Gus about what he meant earlier when he said that she was getting her house back and that's what she wanted. She can't believe that they've never talked about having children before and wants to know why he never brought it up. He says that he was afraid of breaking up their routine, but that he's okay with the way things are now and looking after her children. She doesn't think he should just settle though and they should talk about what he wants. Then, she confesses that, when she watched him with the baby, she imagined them with a little girl. They begin to weigh all their options and worry about the boys being jealous. They go back and forth all day until she finally says that it's really a 'yes' or 'no' answer. Gus says that, if he was ever going to have a baby, he would only want to have one with her. She says that she's never been in such a committed relationship before and planning it out like this would be new for her too. This is enough to make them finally decide that it's a 'yes' and, giddily, they crawl into bed.
