Benedick and Love in Much Ado About Nothing

Throughout Act one and two, Benedick repeatedly says that he will never love a woman or get married. At some stage in the duration of the play his mindset changes. In the end he is head over heels in love for Beatrice whom he once quarrelled with habitually.

Benedick challenges Claudio, previously his closest friend in the world, to duel to the death over Claudio's accusation as to Hero's unethical behaviour. After Beatrice complains to him about...
