The bomber

Antonella

   She's Roberta's ex girlfriend. She's bissexual. Like Roberta, she's a "lowlife". But she's very different. If Roberta wants to protect the "lowlifes" without hurting anyone, Antonella wants the destruction. She hates all the riches from St. Remith for all the humiliation and corruption they do. 

   And for her there is only one solution: burning all of them (in a figurative way of course). 

   She is a hard person, is always with a closed face, and very hard to interact.

   If you want to win her, better start kicking some riches asses.
