Trina Robinson is the best friend of Josslyn Jacks and good friend of Cameron Webber. Trina was known as a 'bad girl' and is first seen throwing an unsupervised party with underage drinking and boys at Josslyn's house. Trina also invited a new student, Oscar Nero, who she knew Josslyn had a crush on. Josslyn and Oscar started talking at the party and began a relationship soon after.
In 2018, Trina was dating a junior and hid some condoms in Josslyn's backpack so Trina's mother wouldn't find them. They fell out of Josslyn's backpack in front of Carly and Josslyn was forced to tell her mom the truth.
Trina was next seen on March 5, 2018 at an alternative prom created by Oscar. He had been defending Dakota, a transgender student, from a bully, Troy Pulver, at school and Oscar wanted a safe place for students to wear what they chose. Troy interrupted the prom but then Oscar punched him and Troy left. Trina seemed to be interested in Dakota at the prom but there was an earthquake and Trina received minor injuries in the aftermath.
After Oscar was diagnosed with cancer, Cameron wanted to help his friend's pain with pot cookies. Cameron heard that Trina's boyfriend knew a weed dealer and he asked Trina for the dealer's number. Cameron met with the dealer, a fellow student named Cole Johnson, and both of them were immediately arrested.
Trina supported both Cameron and Josslyn throughout Oscar's battle with cancer. They all went on a road trip to Niagara Falls as part of Oscar's bucket list. Trina flirted with Cameron during the trip but she could tell he liked Josslyn. Trina also admitted that her 'bad girl' reputation wasn't as true as she made it out to be.
On February 19, 2020, it was revealed that Trina's dad is Marcus Taggert. However, it has been hinted that Trina's biological father is actually Curtis Ashford.
On July 1, 2021, Spencer breaks into the Jerome Gallery while wearing a mask. Nikolas has an alert that tells him about the break-in. Trina later runs into Nikolas in the gallery and pepper sprays him in the face. She apologizes once she realizes it is him and comments that she used all of the spray on him.
Later Spencer creeps around the gallery and Trina runs into him. She tries to spray him but the pepper spray is empty. She throws a remote at his head and sets off Spencer’s trap (fake blood in the sprinkler system).
Trina walks into The Savoy down the street covered in fake blood after chasing after Spencer and losing him. Bartender N'neka helps Trina clean up and get changed for her graduation party.
Spencer goes to Trina's party at The Savoy, entering the back way and scaring Trina. They talk and flirt, with Spencer complimenting her, calling her "badass" and claiming his name is Victor and that he's a barback at the nightclub.
On September 8, 2021, Trina's mother Portia tearfully admitted to an unconscious Jordan Ashford that she needs to tell Trina the truth about her father, hinting that Taggert may not be her biological father.
