At this moment... Rena could have just left and called the police and won... how? she can prove that she attacked in self-defense, her throat was nearly crushed and for that you need the force of the hands that are not damaged, something the doctors can prove... So Rena could have just won here without maybe needing to kill her... but i guess what she will do is quite fair for the situation she is going through... am not blaming her at all here... to go with my suggestion is to be calm when you were just about to be killed... something you can't really ask of a girl her age @_@
