|Andy McNally||Service Record|
She is married to Sam Swarek.
Being a cop is in her blood. It’s all she's ever known and all she ever wanted to be. She is the ultimate rescuer and enabler, but quickly learns that she can't save the world because not everyone wants to be saved.
Meet Andy McNally, who is empathetic (almost to a fault) and a born rescuer, is the star player in 15 Division’s finest batch of rookies. A natural A-student, she's already clashing with her training officer, Sam Swarek, who keeps telling her she's got to learn to trust her instincts. While it never hurts to be prepared, part of being a good cop is learning what you can’t control—which is seriously not easy for this girl. Andy's the daughter of retired beat cop Tommy McNally: her bloodline is the blue line. But Tommy left the force under a cloud, and only Andy knows that now he's hitting the bottle. So Andy is the most positive person on the job—because she knows first-hand where the job can take you, and she doesn’t want to go there. Swarek quietly believes that Andy could be made into a capable officer and though training officers are the forbidden fruit, Andy is feeling the pull of his confidence in her. Because she herself can’t help but wonder after an endless series of screw ups, can she really do this job?
Born Andrea McNally, Andy grew up in Toronto. Her father was a cop like her, and was actually Oliver Shaw's training officer. Her mother left her father when she was 12. It is implied she has a new family somewhere else. It is not clear why her mother left, but it may have something to do with her father's job. It is also possible it has something to do with his alcoholism, but it is unclear whether this started before or after she left. When she was young, her father took her on camping trips out in the woods.
Andy's luck with men may be not so thrilling. She was dating Detective Callaghan, until he cheated on her with his ex Jo Rosati. She has feelings for her training officer, Swarek, and in the last three episodes of season 2, Andy and Sam enter a relationship. Although she is a fighter, she has some weakness when it comes to Sam Swarek... Is she ready for this?
After dancing around a relationship, Sam and Andy take the plunge. Unfortunately, when Sam is in the middle of a dangerous undercover operation, Andy helps find and rescue him from the dangerous Jamie Brennan, but when the two are suspended for three months, Andy realizes that she can't stay in town and obey the orders to avoid Sam. Upon her return from Termagant at the end of their suspensions, the two became an official couple at the start of season 3. When Sam followed Andy's hunch instead of his own instincts and his best friend Jerry Barber was killed as a result, Sam was distraught and began to distance himself from Andy and his other friends at 15. Sam broke up with Andy, leaving her heartbroken and confused in the parking lot of the Penny. After ignoring her calls for weeks, Sam tries to repair the relationship when Andy finds herself in a life and death situation.

While it seems that Sam is immediately conflicted, and realizes that Andy didn't leave for undercover because she no longer has feelings for him, it looks like he may crack, but he continues his relationship with Cruz. When Andy realizes that Sam is no longer an option for her, she finds herself involved with Nick Collins, who has made it clear that he has true feelings for Andy, which jeopardizes her friendship with Nick's ex, Gail Peck.

Sam and Andy
Sam had spent 8 months working undercover as a drug dealer trying to gain information about a drug lord by the name of Anton Hill when he meets Andy McNally for the first time. She believes him to be involved with a murder in the same building and arrests him for possession, unaware that he is an officer as well.
After having his cover blown, Sam returns to 15 Division and is as training officer to McNally. He is very distant and upset with her at the beginning, blaming her for ruining his cover while she in return is annoyed with him regarding his attitude and claims she was only doing her job. Yet, despite their annoyance, there seems to be an underlying attraction between them. He brings her along as he tries to get his informant Emily to leave town since it is a matter of time before Anton Hill finds out she has been spilling the beans to Sam. When Emily goes missing, Sam sends Andy back to the station before going to Anton to rescue Emily. Andy doesn't follow his orders and instead goes to Emily's apartment to locate the files she has on Anton. She then follows Sam to Anton Hill's resturant and exchanges the files for Emily and Sam's life. This impresses Sam greatly and causes him to re-evaluate her. They almost kiss by the end of episode 2 season 1 but Andy backs out at the last minute, stating that its her first week at the job. Sam comments that she's not his type anyway and drives away.
Sam and Andy's relationship grows into an easy friendship yet the attraction is still there, something Gail picks up on. She warns Andy that it is against the rules for a rookie to date her training officer but Andy denies having a relationship with Sam. When detective Luke Callaghan asks her out she agrees while Sam silently watches.
Sam's feelings for Andy continues to grow and he tries to warn her that Luke dates a new rookie every year but it falls to deaf ears. In episode 7, Officer Oliver Shaw and Andy are searching for a missing girl during a black-out. They discover that a man has been abducting and killing girls in the basement. Before backup arives, Oliver is injured and shot, but is protected by his bulletproofed vest. Andy is forced to shoot the killer who dies from his injuries and she is left traumatized. Turning to Luke for comfort, he chooses to work on the case, stating that this was a big case that Andy had solved. Sam meets up with Andy at the lockeroom and comforts her. He tells her to call him if she needs to talk. Distraught, and unable to sleep, Andy turns up at Sam's apartment and kisses him. The pair makes their way up to Sam's bedroom but before anything happens, the power comes back on. As Sam leaves to turn the TV off, Andy recieves a call from Luke but does not answer. Seeing the look on her face, Sam states that everything goes back to normal and Andy gets up and leaves. Their relationship becomes awkward after the blackout. In episode 10, the two talk and make amends.
In season 2, there is still hope for Andy and Sam after the cheating of Luke who was her fiancé at the time.

In the following episode they finally hook up in his undercover apartment. In the mid-ending of season 2 Andy and Sam start to form a romantic relationship, while he is undercover. His cover later gets blown and almost gets him killed. When they both later get suspended for conduct unbecoming, he asks Andy to have a real and normal relationship together. But she leaves him to keep her job. In the beginning of season 3, Andy returns from her 3 month suspension and convinces Sam to re-start their relationship.
After Jerry Barber's death, he starts blaming Andy about his death, and says he needs to stay away from her for a while. Then later outside the Penny, he apologizes to Andy for taking things out on her. Then says he can't be a cop and be with her and breaks up with her. Andy cries as he gets in his truck and leaves her in the rain.

Then he tries to convince her to take him back for another chance and asks for drinks. Andy leaves with Nick for the task force without telling Sam, who is left drinking while waiting for her at the Penny.

Kids, park on Sunday, real life - something more than this. With her." In the season finale Sam finally admits to Andy how he really feels and tells her he can't do "this" anymore. He says that he has to go to let her be happy with Nick. Shortly after this Sam gets shot. Andy refuses to leave his side and goes into the ambulance with him and tells him a story. One night when she had a nightmare he hugged her close and told her he was right here and that he would hold on and never let her go. In that moment she knew that she would never feel more loved or more known. She tells him she loves him and he's her story (he passes out). At the hospital Nick lets Andy go and she waits while they try to save Sam's life.
Season 6 reveals that Sam had gotten Marlo pregnant, and she hid it from him for 2 months. They go to appointments about the baby together, and it puts a dent in Andy and Sam's relationship.
