Ghislaine was on the run to avoid arrest so she was thinking about Ghislaine. I can't think for her, she "may" have thought that the lack of an indictment would have gotten Andrew cleared, I don't know what was running in her mind. I wouldn't be surprised if Ghislaine now figures if she's going down, Giuffre is too or she's going to smear Giuffre to the hilt. The two women were not BFF's at all. Virginia wanted Ghislaine's position and wanted Epstein herself.
