This doesn't actually line up with canon, so I'm just going to ret-con that Katarina doesn't remember the girl she just met when not in disguise.

Not glamorous but Katarina had expected life as a cop to be more interesting. There was crime taking place all over London, so why was she always walking the parking ticket beat and escorting things that never seemed to need the protection.
The ever expected three seventeen a.m. ambulance crew called for police protection and she jumped the case, even though it was probably just a gang roughing someone up and they were probably nowhere near the scene by now.
She and her partner pushed their way through the crowd of bystanders that managed to appear on any scene at any time of day. Probably from taverns, she thought, wrinkling her nose.
She had to fight to keep down her stomach at the heavily lacerated, almost shredded man inside the shady club. Blood always looked worse than it was, she tried to reassure herself. And it was the paramedic’s problem.
“Who attacked him?” she demanded of the ‘keep still behind the bar.
“It… it was a monster,” he blubbered.
“A monster?”
“It was big and had fangs and grr and a masked woman appeared out of nowhere and killed it and disappeared!”
“And the monster’s body just disappeared to?”
“It… it… turned to dust.” The barkeeper gestured around and she could see a layer of powder still around the body. She’d make sure to get out her evidence bags. Probably some kind of drugs.
“It’s true,” said a young girl much more calmly, lighting up a cigarette.
“Who are you?” She couldn’t stop herself from adding, “You shouldn’t be out at this time of right.” Don’t be confrontational, right. Honestly she should be making arrests over the issue though wasn’t going to if she was going to solve the more important case. She managed to avoid a follow-up that this girl shouldn’t be allowed in this club at any time of day.
She snorted. “My parents don’t care where I am. I’m Mina.” She flipped back long, badly dyed blonde hair. She was an Asian female with just a hint of an accent, no more than mid-teens, in a series of leather straps for a top and a short skirt and miles of fishnet.
As Katarina turned to other patrons for their statements, she added, “She, the person who killed the monster, said she was called ‘Sailor V’.”
