[4] She endows his character with elements of Percy Shelley, portraying him sympathetically as "an angelic essence, incapable of wound", who is led by his sensibility onto the political stage.
[6] Lady Gordon stands for the values of friendship, domesticity and equality; through her, Mary Shelley offers a female alternative to the masculine power politics that destroy Richard, as well as the typical historical narrative which only relates those events.

Monina is a versatile young lady who acts as decoy, messenger, and military organizer, in addition to her close friendship with both Richard and Katherine.
