When Amanda asks Laura whether she ever liked some boy, she mentions Jim. She points out his picture in the yearbook in the Pirates of Penzance performance and with a debate trophy. She then tells her mother that Jim used to call her "Blue Roses." Her mother asks why he would call her such a name. She explains that when she missed school due to pleurosis, which is an inflammation of the lining of the lungs or chest cavity, he thought she said "Blue Roses." Thereafter, he called her by that name. When he saw her passing in the halls, he'd yell after her, "Hello, Blue Roses!"
When Laura's brother Tom invites Jim over for supper and he meets Laura again, he says he vaguely remembered seeing her before, but a name other than Laura came to his mind. Laura asks, "Was it Blue Roses?" Jim remembers that's what he called her but can't remember why, so she explains it to him as well.
Jim points out later that Blue Roses is a good name for her. She says blue is wrong for roses, but he says it's right for her because she is unique. He tells her that she's pretty and kisses her. He then explains that he is in love with another girl. His intent only was to increase her self-confidence, but he realizes that he went too far.
