How does Elizabeth’s presence bring Victor back to his Romantic leanings?

Victor and Elizabeth look forward to their union with both pleasure and apprehension. The necessary preparations are made, and the couple determines to honeymoon on the shores of Lake Como, in Italy. Victor takes a number of precautions to protect both himself and his beloved; he becomes accustomed to carrying pistols and daggers about his person wherever he goes.

As the wedding-day approaches, the threat seems to be almost a delusion; Victor allows himself to believe that the marriage will actually take place, and that he will at last know happiness. Elizabeth seems cheerful, but is seized with melancholy on the day that the wedding is to take place.
