History[]
Season 9[]
In Rattle Second City, Gianna arrives at the Firehouse to meet with the chief and some of the staff. She sees Cruz show up late and jokingly says she could pretend not to know him for her first impression. However, she is dismayed by Casey saying that Cruz already told them about their relationship. Gianna also makes food for the squad and Casey is impressed with her cooking. She shares a moment with Blake Gallo. Afterwards, she and Brett answer a call, where they find a man who overdosed. While tending to him, Gianna is scared to watch Brett have a gun held to her head by the man's brother who threatens them to help his brother or die. However, she is amazed that Brett keeps her cool and talks him down before taking the brother to the ambulance to transport him to the hospital. Afterwards, she tries to talk with Gallo again but noticed that he is nervous around the observing Cruz. Gianna decides to make further drama for both of them by jokingly making a date on the weekend. Soon she and Brett are called to another case before her stalker appears behind her and his truck and rams them off the road.
As of That Kind of Heat, Gianna and Brett are shown to have survived the crash. However, they are trapped inside the down ambulance but after breaking free they start to wonder if the gunman is still out there. Soon they are able to get free before Casey and the rest of the team show up. They also find out the gunman is still trapped in his car, where he is begging for help while despite his actions Sylvie frees him and gets him the medical attention he deserves. Gallo also bandages her up and the two go back to the house, rather than going to Chicago Med. Later on, Gianna blows off her stress by exercising at the football stadium. She soon says she is unsure on whether to stay at the house or transferring but Cruz brings up his promise to her brother and reassures her. At Molly's, Cruz gives Gianna support and promises not to be too overprotective. Gianna then turned her gaze to Gallo who is not too far from the conversation and once again Cruz voices disapproval, but she is not deterred.
During Smash Therapy, she and Brett answer a case with Gianna taking note of the awkwardness between her and Casey. She was later informed about the pairs relationship but understands mentioning her own personal troubles. During this talk she asks Brett if Gallo was seeing anyone, to which Brett confirmed that he was not. Much later, they are shown to bond when Gianna allows Brett to destroy a drone (that previously did damage to a woman's nose) to vent her frustrations. Afterwards, Brett thanked her for the support. Gianna accepted before noticing Gallo and asks if she gave him her number would he call but he turned her down. Brett told her not to give up on pursuing Gallo.
In Funny What Things Remind Us, Gianna answers a call along with Brett. Much later, she is amused by the pranks of Mouch and his rival Rutledge. During a case of the construction yard, Gianna is nearly caught in an explosion, but is saved when Gallo came to her aid. Gianna is amazed by how he risked his life to save her.
In Blow This Up Somehow, Gianna and Brett accompanied the squad to a fire where Gianna told Gallo of a trapped victim. After the whole situation was taken care of she asked Gallo to tell her a story about how he saved the victim. However, this brings consequences as Casey suspends Gallo for disobeying orders and nearly getting himself killed. She felt guilty about this, but temporarily put it aside when a case occurred. Gianna found it odd when a woman who was having a seizure spontaneously got up before she and her boyfriend leave. Much later, the two answer another call in a man who had a bad leg injury, but he does not react to the drugs even when they gave him the high dosage. That night, she visits Gallo who was reprimanded by Casey. The two end up hooking up. Chief paramedic Colson later tells Brett that Gianna may have been stealing the drugs, which is why the man didn’t have a reaction. However, Brett and Gianna both realize with help from Joe that the couple with the seizure were actually scam artists who stole the drugs while they were distracted. After some investigating, they find the couple with another set of paramedics. Jumping into action, they immediately tell the other paramedics that they were just ripped off and their drugs were stolen. This is immediately confirmed with the paramedics finding the drugs gone. Gianna immediately makes sure the couple do not leave and taunts them when the cops and chief paramedic arrive. The cops located the drugs in the pockets of the boyfriend and arrest the couple. At Molly's, Gianna thanks Brett for having her back through the entire ordeal and the latter tells her she will always do so. Grateful, Gianna then asked Brett about her situation with Casey and Brett is she in case he had a little thing going before she broke it off and she’s confused on what to do now when seeing him with another woman. Gianna encourages her to go have some fun of own in order to move on, something she agrees to. When Joe arrives to talk to Giana about Gallo, Brett leaves them while Gianna jokingly asks what happened to having her back. She prepared to talk with her irritated friend.
