The final scene of this episode allows Lacey Chabert (Claudia) to show off her passionate singing voice as she sings "Have Yourself a Very Merry Christmas" with Julia. In previous interviews, Chabert has acknowledged that singing was always her first love, and that's what she wanted to do first and foremost, but she just happened to fall into acting, too.
Bailey: Fine, I'll stop by sometime.
Julia: Oh, that's great. Another one of your "drive-bys."
Bailey: What do you want from me?
Julia: I want you to come home for Christmas.
Bailey: I'm not doing Christmas this year.
Julia: Oh, get over yourself, Bailey, okay?
