After Linus and Mimi spend time gardening together, Linus invites her to his birthday party which she accepts. Linus keeps hearing Mimi's singing voice everywhere he goes and can't seem to stop thinking about her. As Linus is writing his guest list for his birthday party, Lucy asks who Mimi is. After Linus tells her, Lucy thinks that it's ridiculous that Linus is inviting a girl that he just met and thinks Mimi will not show up, but Linus is positive that she will.
