Jane Moore Visits her Brother and Sister
Jane Moore is estimated to see her siblings in July of 2001 because she hasn't seen either of them since the death of her parents in January when her brother, Mark, inherited the family home, and the "minute he sold it, he disappeared" (Lindner 3). Additionally, after seeing her siblings, Jane laments that, "if either of them had been interested in what [she'd] been doing with [herself] for the past six months, it would have made [her] happy," so readers know she's been working for Nico for approximately two months at this point and it’s six months after January in the narrative present (Lindner 194).
In Jane, Jenna and Mark are manifestations of Georgiana, Louise, and John from Jane Eyre, so predictably, they are cruel and cold to her. Jenna uses Jane as a mediator between her and Mark yet refuses to house her in her swanky NYC apartment, forcing Jane, who is only there because of her, to dip into her dwindling savings to put herself up in a hotel.
Mark gaslights Jane regarding her memories of him abusing her throughout childhood and announces his violent misogyny repeatedly. Jane is still fearful enough of him that she insists on meeting him in a public location. Like the hypotext's John, Mark is an alcoholic and can't hold down a job or earn any money after blowing through his inheritance. An important distinction though, is that in Jane Eyre Georgiana and Louise at least change slightly, whereas Jenna is "self-absorbed and demanding" like always (Lindner 186).
