The main difficulty with Zenia is that we only learn about her from the viewpoints of Roz, Charis, and Tony. And given what Zenia has done to all three women, none of their accounts can really be considered objective or reliable.
This is important because, by the time we get to the end of the book, almost everything we think we know about Zenia has been implied–Atwood gives us very little concrete information about her. Certainly, we know that Zenia lies. She tells a different story about her childhood and upbringing to each of the three women, carefully designed in each case to elicit that particular woman’s sympathies. She shows up in Charis’s yoga class with a black eye that she claimed to have gotten while living with (Tony’s husband) West; later Charis learns that at that time West had not seen Zenia in a year and a half.
In fact, the fact that she lies is nearly the only concrete thing that we know about Zenia. Well; there may be a few other things we know:
* She lies. To everyone.
* She exploits people to get what she needs / wants, both implicitly through carefully crafted deception and explicitly through what is essentially blackmail.
* She seems to need a lot of money and engages in deceptive and otherwise morally questionable behavior.
* At some point after college, she had breast implants and a nose job.
* At the end of the book, she ends up dead in the hotel fountain (presumably having fallen to her death from her balcony).
What else do we have to go on? Only what she says–which can never be taken at face value–and what we are invited to imply from the accounts of the three women upon whom she has inflicted serious emotional damage.
For the record, I think it’s important to note the judgments that Atwood seems to want us to make about Zenia’s character. We are supposed to see her as
* sexually experienced, aggressive, powerful, and promiscuous. In short: a slut.
* having an inferiority complex. Hence continually feeling the need to make up tragic stories about herself and her life in order to impress (and gain sympathy from) others, and to target and “steal” the lovers of women she knew in college.
* feeling out of control. Hence the need to attract and control men, especially men that are “off limits”–almost as if she needs a challenge to prove to herself that she is in control. Of whoever she wants.
* hedonistic and impulsive. Hence the sudden appearances and disappearances, and intricate (and not-so-intricate) plots to exhort money from others.
* antisocial in the sense that she shows little or no concern for the well-being or happiness of other people.
Some of these might be true (whatever “truth” about a character in a work of fiction means). Some may be red herrings. My point is, it’s all speculation and implication.
What we don’t know about Zenia could fill the LA phone book. Some particularly interesting things about her that we don’t know include
* her last name (for crying out loud).
* her nationality and heritage.
* pretty much anything about her childhood and upbringing.
* what she was really doing during the time she didn’t spend seducing West, Billy, or Mitch.
* why she targeted West, Billy, and Mitch in the first place.
* why she faked her death.
* how she ended up actually dead at the end of the book.
