Regarding what happened that night after getting drunk, it obviously cast a shadow on her, so she repeatedly reminded him he was drunk.
But he wasn't drunk, not only was he not drunk, but he had never been so clear-headed in the past thirty-two years!
After that day of inexplicable rage at Grace Parker, he couldn't understand his behavior, so he left for three days.
Those were the longest three days, and upon returning to see her, his emotions were very complicated.
Clearly, a woman he initially disliked greatly suddenly walked into his life, and now, he found he couldn't ignore her.
This realization left him at a loss, unwilling to delve into why, so he returned late every day, seeing her as though not seeing her, striving to ignore her.
Yet she kept talking to him time and again, though only a "good night," each time it struck his heart.
