Director at CatCo
At work, Andrea wanted a sexy story of a murder when coming across billionaire Niles Jarrod who died at a club, she waved it off as nothing important, Kara Danvers and William Dey find themselves in a verbal altercation. William told the room he has already looked into the story, and there is nothing there.
After that Rip Roar was incarcerated in the D.E.O., Andrea was tasked by Leviathan to kill Russell. As a shadow, she tried to break in the D.E.O. by herself but failed due to Supergirl's interference. Andrea asked Lena as a friend to help her break in the D.E.O. by distracting Supergirl. Andrea manage to get Russell out of there and gave Lena the medallion as the favor and reminded her that the medallion is a curse. When Andrea tried to get Russell in a plane to escape Leviathan, Russell was shot and the messenger tells her that the power never came from the medallion but just activated her darkness and she can't escape it.
She took the Medallion of Acrata like in the original multiverse, however she was never contacted by Leviathan after she took the Medallion of Acrata.
During a briefing to increase Obsidian North's "Collective Dream" VR lenses, Andrea is interrupted by her old college mentor and friend Gemma Cooper. She excuses the room as the two catch up. Gemma examines her work with VR lenses and brings up the idea of creating a space and a new reality for people to escape to permanently that are unable to function in normal society. 
Andrea is very surprised and pleased to have a meeting with her former friend Lena, who apologizes for how she blew up on her 10 years ago and friendship. They are quick to patch things up, and Lane offers if there's anything she can help with her new powers, or Leviathan, and Andrea thanks her for her kindness. She later calls Kate and William into her office, informing Kate should will be running at receiving article on their former employee and her former friend, Winn now that he is a wanted fugitive. Kara protests, but Andrea demands she do it.  After finding some small bugs in the system, like the tasting of food, Andrea orders more workup and studies to be conducted with Kelly Olsen. Later that day she is visited by her friend Lena, hoping to see the latest upgraded model. When she tells her of the complications, she offers to help, but she politely declines. Days later her mentor and boss calls, Gemma calls her, demanding to know why she declined help from the Luther’s. She apologizes and calls her friend for assistance. 
While at work in preparing to launch her Obsidian Platinum lenses, she is attacked by a mystical force in her private elevator but saved by Supergirl. Refusing to quarantine herself for her own safety, Supergirl is assigned to protect her for the day. After being attacked during a sitdown interview, she confesses to supergirl who wants her to remove herself publicly for safety, why this launch is so incredibly important to her. She agrees and after being attacked for a third time, is stashed away at the DEO much to her annoyance. Unbeknown to her, her product was being sabotaged by a refugee alien who's husband committed suicide in part due to her obsidian lenses.  Andrea continues to work on her research in private.  The next day Andrea is reminded of an unattended glitch from two months ago where a person was unable to exit his obsidian lenses. She insist the problem has been fixed, and it's just bureaucracy holding up the money. After coming to the conclusion that similar problems have happened, she demands nothing else goes forward until the escape glitch is fixed. 
Andrea was once a kind and caring individual, she moonlighted as an invisible assassin working for Leviathan, she was recruited by this organization like Eve Teschmacher was, both of them are doing things against their will and in exchange for helping them out financially, both of them were victims that came with a price, as she felt bad about betraying Lena Luthor and even apologized to her. Even though Lena never forgave her.
Andrea has a strict code on how she handles her employees, if they did not meet her standards, they have the free-will to walk out of the job. Because Kara Danvers' report writing did not meet her standards, she hired William Dey to rewrite Kara's report entirely. Mostly she is secretly working on a terrorist plot.
