At home, Kevin's setting the dining room table while Joan practices piano in the background. I never noticed that the Girardis had a piano, but then, it's not the sort of thing I usually pay attention to. Helen, who's preparing supper in the kitchen with Luke, says, "I've learned with your sister it's best not to ask. She might try to explain." Joan hits some wrong notes and bangs the keyboard. Kevin, hopefully: "Maybe she broke it." But she starts up again. Helen mentions that their insurance company called to tell them that Kevin needs pre-approval for the second opinion he's seeking. He says he'll take care of it. Helen wants to know why he needs a second opinion. Kevin evades the question and insists he'll handle it. Joan comes into the dining room, asking if something's wrong. Kevin says no. Will comes in the front door and asks if someone was playing the piano: "I thought I heard…" Kevin: "Pounding? You heard pounding." Joan: "I'm doing a lot better." Kevin: "At pounding." Joan: "You want me to do well in math, don't you?" Helen says, mostly to herself, "This is why I don't ask." Luke, who wouldn't miss an opening like that: "Well, all music is based on the mathematical certainty that vibrations change when the ratio between whole numbers change." (Luke is wearing an awesome t-shirt with an anatomical graphic of the organs in the torso on it.) Joan comes to the dining room, saying, "Ahhh…and Joan flunks math!" She asks Kevin, "So…what's wrong with you, anyway?" Will calls from the kitchen, "Something wrong?" Kevin insists he's fine. He wheels away. Please note that the powers that be have heeded Sars's plea, and Kevin is now sporting some sideburns. ["I know. Sometimes the answer is yes, too." -- Sars] Or maybe Jason Ritter took it upon himself. Joan asks, "Did we join the CIA and I just didn't get the note?" Helen asks what she's talking about. Joan: "Secret doctors…" How would she have even figured out that much of the conversation? She was playing the piano when Helen was talking about it. She continues, "The mysterious…Richard…" Luke asks, "Who?" Joan says it's some relative of their father's that their mother won't discuss. Will tries to act casual: "Why are you asking about Richard?" Helen tells him about Joan finding the letter. Will asks what it was doing there. Joan: "So who is he? A criminal? A pervert? What?" Will says, as he pours himself a drink, that he's a distant relative. Joan: "He's a Girardi?" Will claims again that he's a distant relative: "I barely knew him." Joan persists: "Grandpa said in the letter you were mad at am." Will shrugs: "Stuff happens when you're young." You can tell Joan's not buying it. He changes the subject: "Can we eat? I didn't have any lunch." Then the scene just fades out abruptly.
