I'm working on the theory that CZ still reacts and feels as she did as Laurie even though she doesn't remember why, but that's all overlaid with what she does remember of her ordeals.

Laurie started life as a trailer park girl with little future. Offered a deal by the Hooded Hood she became one of the generation of "New Battlers", with the attitude and abuse that entailed. Despite an unhealthy relationship with Battler's leader E-Male she "got out" long before Samantha Bonnington and then interned with Lisa. She had a complicated and tempestuous relationship with Goldeneyed that culminated in the birth of a child whom she was convinced to give up to the Order of the Observing Eye and who has never been found since. After her split from G-Eyed because of her choice regarding her child she became very depressed. This led to her drug addiction, to prostitution, and to her exploitation in porn movies. After she was saved from a starring role in a superheroine snuff movie she slowly recovered with the help of her room-mate, Beth Shellett (who was subsequently revealed to be Commissioner Graham's estranged daughter, and who G-Eyed once intended to marry). She confronted E-Male and was horribly disfigured and nearly died; later she was healed by Princess Uhuna and killed E-Male. Laurie was betrayed when she was deceived into a relationship with Blackhearted, an alternate dimension version of G-Eyed whom she assumed to be the real thing. Thereafter she was captured by Baroness von Zemo, who mined her memories to be able to pass as Laurie to infiltrate the Lair Legion as Citizen Z during the Parody War. Laurie herself was sold to demons and her fate was unknown.

As Amnesia she somehow ended up in the past as an inmate of Herringcarp Asylum. There she met various aspects of the Hooded Hood before they came together to form the present archvillain; in particular she became the lover of the cruel Marquis de Herringcarp. She was last seen captured by the sinister Herringcarp inquisition and her fate from that point is still untold (probably until Hallowe'en). A ghost version of Amnesia has haunted Herringcarp since but has only become active, aware, and able to project beyond the boundaries of the site in the last couple of years. Amnesia appears to have an uneasy and unpleasant relationship with the Asylum and a complicated detente with its principal inmate, the Hooded Hood. The cowled crime czar's plans for Amnesia may be different from those the Asylum has.

So Laurie has often been willing to use "new school" methods superheroing from her earliest days. She's certainly been willing to use lethal force against those who have done her wrong. She's learned to be distrustful, to avoid "crutches" be they drugs, teams, or people. Every time she's had a "good" break in her life it's turned sour and hurt her.

I'd suggest that's why she's in some ways the opposite of CSFB!. After all, he's had similar experiences but has ended up with a loving family, many friends, public popularity, respect, self-confidence etc. He's the poster child for bouncing back.

I'm building the new Legion roster with some built-in character conflicts; you've identified one of them.
