Victoria is Leia. Leia was long feeling the heat due to her criminal underworld activities, with numerous death threats from rival gangs and the police closing in. It was then that Leia hatched a plan to undergo EXTREME cosmetic surgery to take over the persona of Victoria Frohn - a child who died in infancy. Thus, she could continue to control her empire from the shadows, while getting employees, friends, and family to drop her name ("Leia") occasionally, so not to arouse suspicion.
Leia/Victoria was extremely pissed that Ocean deleted all incest from WIAB so she thought she could get back at Ocean by seducing and bedding Nika - the son she had with William.
All was well until someone in Leia/Victoria's organisation ratted her out to her enemies, who then hired contract killer Marla (who uses a teaching position as a cover) to terminate Leia/Victoria with extreme prejudice.
Only Marla botched the job - her first failed contract ever. Marla, normally ice-cold and calculating, is now plagued with self-doubt and seeks therapy.
Meanwhile, Leia/Victoria is having to formulate a new plan, now that her cover is blown. To buy time, she feigns paralysis and hopes this will make her enemies pause.
How do I know all this? I think it's obvious. Both Leia and Victoria have really big boobies.
