Gruadh knows she will likely not be included in the historical record because she is a woman. She also is aware that, because Macbeth died just as Malcolm came to power, Malcolm will do his best to ruin Macbeth’s legacy and elevate his own. This is a sort of meta-commentar,y as historically Gruadh was left out of the record and Macbeth’s legacy was permanently corrupted by Shakespeare’s tragedy,
Macbeth.
