It looks like Jacques was into really young girls lately. Brianna would have been too old. I think that "Breckinridge" is derived from the novel and movie "Myra Breckinridge" about a person who has a sex-change operation. Jacques and Gagnon perhaps would have preferred to have sex with boys, but couldn't quite cope with that so they selected pre-pubescent girls. The cousin hit puberty and Jacques had to look for a replacement. The woman that Jacques had raped years ago was 18, but my hunch is that his current appetite, that he shared with Gagnon, was for younger girls.
