In season 5, Lauren changed her hairstyle to a shoulder-length edgy hairstyle with bangs. She found out that the cosmic string was their home the Victory was able to break free, and after the aliens left, her powers returned and she began a relationship with Justin. Crusher asked her to use her Human abilities to try to determine the aliens' intentions. They were heading for a cosmic string which would destroy the Victory. She temporarily lost her psychic powers when she came in contact with two-dimensional lifeforms that had caught the Enterprise in their magnetic force. Justin was able to send a message to Enterprise giving them the location of the Ferengi ship, and they were rescued. They used mind probes on Lauren and Vicotria. They wanted to use Lwaxana's telepathic abilities to give them an advantage in negotiations. While attending a trade conference back in Melbourne, she, her mother, Victoria, and a newly-single Justin Macleod were captured by the Ferengi. He had found a way to relieve his mental pain and Tin Man had a companion. After boarding the organism, Tam bonded with the alien and remained with it. Having lost its crew years ago, Tin Man, as the organism was called, wanted to die and waited by a star that would shortly explode. She met him again when he was being transported by the Enterprise to make first contact with an alien lifeform that looked like an organic spaceship. While studying at the University of Melbourne, one of her patients was Tam Elbrun, a Betazoid male who had been suffering from mental instability due to his lack of the Betazoid's natural ability to 'tune out' the thoughts of others. Lauren began studying psychology sometime in the late 2360s and early 2370's. Ral quickly left and bid goodbye to Johansson. The Barzan gave the right to Ral, but it was soon discovered that the wormhole was unstable and worthless. When the Ferengi threatened to blow up the wormhole, stating that there was a secret deal between the Federation and the Barzan, Lauren suspected that this was staged by Ral to acquire the rights to the wormhole. She learned that he was part Betazoid and had been using his mental powers to influence the negotiations. Ral and Johansson each had an instant attraction for each other. The next year she fell for a delegate, Devinoni Ral, at a conference for the rights to a wormhole.

When she joined the Victory, she became friends with Horton's then-boyfriend, Justin Macleod. In 2394, after Michael Donaldson left the Victory-D to head Starfleet Medical and Sharise Bryant was killed in action, Commander Johansson and Lieutenant Commander Kaycee Horton, who was just 19 at the time, were assigned to the Victory-D as chief counselor in 2364, while Horton became the CMO. Lauren was assigned to Starbase 45 where she befriended a med school graduate Kaycee Horton. Later that year, she served with a senior officer named Masc. In the same year, Johansson graduated from the Academy. During her time at the prison, Deanna studied Hent Tevren, a Betazoid psychopath who had the ability to kill telepathically.

In 2372, Lauren began a four-month advanced behavioral psychology internship at Darona's prison facility for the criminally insane. Johansson majored in psychology at the Melbourne University.

Lauren entered Starfleet Academy in 2368, at age 18.

Sadly, William Johansson died from heart failure when she was eight years of age.Дuring her senior year at Melbourne High School, Lauren tells her mother that instead of going to Melbourne University like her older sister, Veronica, she decided to do something with her life with some meaning, by attending Starfleet Academy. The last time Laure spoke to her father, he promised to return home with a surprise. Deanna's favorite books were in the Cowboy Ralph series, written by an author named Ernest Pratt and her favorite song was Down in the Valley. One of Lauren's favorite pastimes growing up was having her father, Will, read stories to her about Earth's ancient west era and singing songs of the era. Lauren Johansson, a native Australian, and the second daughter of veteran Starfleet Admiral Victoria and William Johansson, was born on March 29th 2350, in Melbourne.
