Who is Jenny Shin in the novel, All This Could Be Different?

Jenny Shin is Marina's ex-girlfriend, and she is significant in the novel as a foil of sorts to Sneha. When Sneha first meets Jenny it is as a chance encounter; Sneha and Tig are out to lunch when they catch sight of Jenny slapping Marina and intervene, prompting Jenny to make a racist comment to Tig and run out of the restaurant. Jenny's cruelty toward Marina has lingering psychological effects on her that affect her relationship with Sneha, and there are also respects in which Jenny's overt racism is used as a comparison for Sneha's more covert racism.
