Picard, a disciplined and private person is human after all and falls hopelessly in love, in spite of his reserved nature. With true love nobody is immune. And if Wendy Hughes is around I don't know how anybody could resist her in a great role and beautifully written episode. Of course our Captain can't just walk off in the sunset and the connection with his other "life" from "The Inner Light" episode is another reminder that the Captain of the Enterprise is a lonely place to be and Picard had to sacrifice a more normal existence long ago.
