 Frasier and Diane bring Dr. Bennett Ludlow, Frasier s mentor, to the bar for a drink. Both Frasier and Diane are in awe of the man and obsess about the smallest social issues with him, like how to tell him he s got a crumb on his tie. But it s Carla with who Dr. Ludlow is obsessed. Two weeks after that night, Carla has been getting expensive flowers from a secret admirer, and Dr. Ludlow has been canceling plans with Frasier and Diane. Frasier and Diane think that Dr. Ludlow doesn t want them as social companions. However Sam suggests that the coincidence between Carla s flowers, the nights she wants off and the nights where Dr. Ludlow cancels plans with Frasier and Diane is just a little too much. Could Dr. Ludlow be Carla s secret admirer? Frasier and Diane think the idea ludicrous. They learn that night by witnessing Dr. Ludlow and Carla s embrace that Sam is indeed right, much to Diane and Frasier s horror. Frasier implies to Dr. Ludlow that he would be better to return to his own social circle after this walk on the wild side, but they all, including Frasier and Diane, come to accept and support the relationship once Dr. Ludlow announces that he plans on asking Carla to marry him after returning from a short trip. On the night Dr. Ludlow plans on asking, Carla is late, apparently in more ways than one: she s pregnant again, with Dr. Ludlow s baby. Before she tells him about the baby, he does ask her. Thinking that it a good idea for the marriage, she tells him the truth, which also does include that she has five other children, a fact she hadn t mentioned to him previously. Although taken aback, he still wants to marry her. She s stunned at his class compared to other guys she s dated, but can t say yes. She tells him she s in love with someone else, really implying that she doesn t love him. So she s unmarried and pregnant again, the continual saga of Carla Tortelli.
