If she was going to get out of the horrible situation, Hermione knew that she had to be smart about her next actions. She was fully aware of the fact that if it came down to her life being in jeopardy, both Augustus and Antonin would be at her defense.

Playing some long, drawn-out, horrible game where the winners got to continue living and playing while the losers no longer had to worry about their next moves.
