PerForMeg -- it's an interesting question of why Giorgio falls in love with Fosca. On the London cast recording, there's a song that I don't think is in the Broadway version (I listen to the London one WAY more because the cast is so fantastic). Giorgio sings:
"No one has ever loved me,
As that woman has.
No one has truly loved me, till Fosca.
Love without reason, love without mercy,
Love without pride or shame,
Love unconcerned with being returned,
No wisdom, no judgement, no caution, no blame.
No one has ever known me as that woman has....
I was wrong, love's a demand, I was wrong.
Love needn't grow,
LOVE CAN BE SUDDEN SURRENDER NOT TENDER NOT SLOW
AND I KNOW NOW THAT I LOVE FOSCA.
Not the way that she loves me,
But I love Fosca, and nothing will come of it."
From this, I would gather two things. 1)The love he feels for her just hits him -- which is kind of the point of the whole show. His meetings with Clara were PLANNED, his love with her was very regulated. This love with Fosca is beyond control, beyond planning or organizing. In other words, THERE IS NO explanation for it. 2) Love sometimes does come as a result of someone else looking at you in a way that others don't. I think most people's reaction to a love like Fosca's would be one of two things: repulsion or attraction. Her love was extreme, so his reaction had to match it. Repulsion changed into love BECAUSE Giorgio realized that Fosca's love was the opposite of what he had with Clara -- what he mistook for love from her, wasn't really love. She would not compromise for it, she wouldn't leave her husband -- she was bound to societal rules. Fosca was the opposite -- devoted and raw -- it was a powerful force that he had never experienced before.
I hope that makes sense -- or at least gives you something to think about...
