You might think its weird that Boudica says love here, but I think we'll need to see what she actually means in next chapter. Obviously it doesn't mean she fallen in love with Nero or anything. She might just talking of herself as loving person, her true self before her tragedy happens. Instead of falling into her vengeful self she manages to stay true to her heroic and loving self. As a mother and a hero. The former can be tied to Nero's character who has mother complex, and also in this chapter questioning what love means.
