Tina McGee (Earth-90)

Christina R. "Tina" McGee was a scientist at STAR Labs and the wife of Barry Allen.

Early Life
During her years in college she met and befriended David and Carl Tanner though later, she would eventually get into a romantic relationship with David.

At some point, she took interest in the science of mind control from Marcos Trachmann and learned that the mind control ship could kill the animals on which it was used with excess.

At some point in 1989, she and David got married and both eventually became scientist that work for STAR Labs.

In 1989, her husband David discovered a special enzyme that can stimulate the human's brain and enhance his senses. Tina and her husband were ordered by the government to test the enzyme on human subjects, but because they refused, the government cut their funding until they agree to do the test. One morning, Tina found David's body in the lab due to him serving as the test subject for the enzyme. This would cause S.T.A.R. Labs reputation to decline to the point where Tina was the last scientist in the building.

Meeting Barry Allen and birth of the Flash
In 1990, a doctor from the city's hospital contacted Tina about someone that got struck by lightning and has some form of cellular damage. Later, the doctor would warn her that the patient Barry Allen has declined to come to STAR Labs. Days later, Barry would eventually accept her call and come to STAR Labs. When they first met, they are both surprised about their appearances then they entered the building. Barry misjudged STAR Labs due to the incident that led to the death of someone last year until he realized that it was Tina's husband. She placed Barry on a treadmill in order to test his "speed" and see how fast he could run but due to Barry running too fast, the treadmill broke. After some few tests, she and Barry went to eat at a pizza place due to his low blood pressure, and she told Barry to keep his abilities a secret because the last time the government discovered something, it caused her husband's death. The next day, Tina and Barry were at STAR Labs test track and equipped Barry with an abandoned Soviet prototype deep-sea suit in order for his body to handle the heat. After some few laps, Barry took Tina but because she is not equipped to handle the speed, her clothes got torn apart. They then talked about how Barry felled about the speed but before he could finish his sentence, Barry almost pass out. Barry brought Tina to the precinct where she met Julio Mendez, Barry's best friend. She noticed that the lab's computer identified a sample belonging to Nicholas Pike which Barry recognized to be his brother former partner that went rogue. After Barry deduced that Pike was planning to murder his brother in an ambush, Tina tried to warn him that it was dangerous to go by himself. Days later, Barry came to S.T.A.R. Labs and asked Tina if she could add gloves and a hood in order to conceal his identity and bring Pike to justice. He then asked her to add an emblem on his chest that represent a bolt of lightning. During the night, Barry got injured at the leg and Tina received a notification about Barry's injury, and she went to find him only to see that his colleague brought him back to his apartment. Tina entered Barry apartment and told him that she would like to check out his leg and met Iris West that was already waiting Barry inside his apartment. The following day, Barry would pass out again but got the time to call Tina before passing out. At STAR Labs, Tina told Barry that his metabolism cause him to pass out if he doesn't eat enough. Despite Tina's warning about the metabolism effect, Barry ignored her and went after Pike again as "The Flash". Later, after Pike arrest, Barry went to apologize to Tina for ignoring the warning that almost cost his life and told her that he has faith in her to uncover other sides effects.

The homeless disappearance
The next week, Tina attended a lecture from Carl Tanner that recently moved to Central City. She invited Barry despite him being late at the lecture on mutation. After the lecture, Tina introduced Barry to Carl who started to argue about the science morality. Carl then proposed to bring Tina to her home and Tina accepted to Barry's frustration. At her place, Carl revealed that she was still in love with her, but she felt awkward about it and closed the door leaving Carl outside while she thought about her late husband. Days later, she helped Charlie Wright get a job as a security guard. Barry asked her out for dinner, but she revealed that Carl already invited her to dinner earlier and left the lab. During dinner, Carl asked Tina if she could get him David's note since he realized that their research are very close. Tina refused and left the dinner but only after Carl gave her a glass of wine that she "forgot to drink". Tina woke up later at her apartment and realized that she felt asleep after taking one glass of wine and Carl told her that it's fine and that he brought her home. In the morning, she came to the lab after a break in happened, and she confirmed that nothing important was missing. When she noticed David's note left on the printer, she warned Barry about it. Barry pointed out that Carl could be the only one responsible and Tina assumed that Barry was just jealous and after a heated argument, she dissolved their partnership. Later, Barry brought a dog that has mutated and Tina recognized the cells to correspond with those of David's formula. Tina apologized to Barry and accepted the fact that Carl was the one behind the homeless disappearance. Some time later, Carl entered STAR Labs to obtain the equipment necessary to ionize the mutation formula. He revealed that he knew what it was being a homeless because he used to be one during his youth and when Tina tried to stop him, he slapped her and tied her to a chair. Later he demonstrated the effect and turned himself into a mutated monster. Carl tried to turn her into a monster but the Flash came and saved her and fought off Carl. After Barry managed to immobilize Carl in a homeless alley, Tina tried to reason him, but he rejected her and told her to leave him alone. Tina then cried and hugged Barry waiting for the police to arrive.

The Fires
During the time when mysterious fires happened around the city, Tina was in her office trying to call her assistant Sherry to give Dr. Carter Hall a message about her whereabouts. She realized that an intern called "Heather" replaced her but caused an incident that made Tina mad enough to leave the room. The next day, Barry visited her at STAR Lab and told her about Castillo's blackmail and about how dangerous it could be for all his close one including Tina. The next night, Tina caught "Heather" talking to intruder until "Heather" told her that those men wants to kill her. After fighting off the two assassins, they both went inside "Heather"'s truck and escape. At the precinct, Tina now informed about Megan's story and aware of the current situation, she asked Barry to explain what was going on. Barry told her that Gambling will soon be legalized and that Simonson is burning down building before purchasing it and thus giving him the possibility to create a legal Casino. Mad at Megan, Barry left the room at super speed and Megan asked if that was always weird and Tina said "all the time".

The Museum theft
When the Death Mask of Rasputin was about to be placed on display at the Central City Museum, Barry came after midnight to the lab to talk with Tina. She learned that in his youth, Barry used to work at the museum and was a friend of Ted Preminger who was now the museum curator. Barry blamed himself for joining the police forces and abandoning his friend but Tina supported him stating that in the end, he followed both studies and ended up half archaeologist and half a police scientist. Though someone broke into the lab with explosives and Barry as the Flash had to intervene. She eventually learned the next day that the materials that were stolen at the lab could be assembled into a cutting laser. Barry deduced that the gang of thieves stoled the materials to rob the museum. When Barry as the Flash managed to defeat all member of the group of thieves, Ted Preminger contacted her about an shoulder injury. Days later, she and Barry waited Shawn Allen ouside the museum while he was visiting it. tina commented that "The Flash"'s name is probably going to stick to Barry and stated that she found it "sexy".

Day of the Dead Festival
At the beginning of the Day of the Dead Festival on November 2, 1990, Tina was invited by Barry to eat at a Mexican restaurant at the Hispanic part of Central City. After the diner, she left Barry by taking a taxi while he was investigating some grafities that appeared around the city and promised that he would go with her to the theater in hald an hour. Due to Barry not showing up at the theater, Tina came to Barry's apartment the following morning and he revealed that he did received a note that involved the Flash's appearance on the case which was why Barry did not call Tina. But Barry also revealed that he had a blackout and Tina tried to make him worry about it but he believed that it was fine after he ate some cereals. Barry was unable to explain that blackout and had to go to work due to an incident to the local Hispanic church. In the afternoon, Tina tried to call Barry multiple times, but he was unable to answer. After he finally took one of her calls, he revealed that he lost 8 hours due to a blackout. Later, at STAR Labs, he tries to test how his body responded when his eyes were hidden and discovered that with his left eye, he can't control his hands. Tina deduced that it has something to do with some parts of his brain that does not communicate with the rest of the body. Barry became mad after this and blamed that effect on his abilities. Tina then found some kind of mark behind his neck and asked if that was due to an insect bite. Yet again, Barry had to leave due to work and Tina told him that he was her best friend but also her worst patient. Later that night, Barry brought Paloma Aguilar to the lab in order to protect her from Reuben Calderon. After a test on Barry's body, he left for work and Tina told him that even though Paloma was in danger, he wasn't capable of protecting himself. After he left, a moment later, he came back dressed as the Flash and hit Tina knocking her out. Once she woke up, she realized that Paloma was gone and Barry came back worried about another blackout, and he also noticed the injury at her head. Tina then showed him some camera footage that revealed that Barry was the one that hit her and kidnapped Paloma. After that she exposed Barry to a machine that tried to make him remember what happened during the blackout. Tina then showed him the result of the test earlier that revealed a tiny microwave receiver inside Barry's brain. Angry at this, Barry left to find the one responsible for those events. Later, Tina successfully jammed the signal inside Barry's brain which saved his life just in time. Barry then came back to STAR Labs and thanked her. Tina then revealed that the time bomb inside Barry's brain could go on at any minute due to his metabolism accelerating the process. At midnight, when Barry as the Flash was under mind control again, Tina jammed the signal again and minutes later, Barry who successfully saved Aguilar, asked Tina to remove the ship inside his brain and the one inside Paloma's. The next day, they celebrated Calderon's arrest at the restaurant they went earlier with the rest of Aguilar's family.
