S5E7 : Calamity over the Comstock

Joe has a run-in with Calamity Jane, and takes her home with him after promising her dying father to take care of her. At first the Cartwrights (besides Joe) think ""Cal"" is a boy, but they soon find out differently. Cal begins to fall in love with Joe, but Joe finds her attentions unwanted...especially when Cal's boyfriend, Doc Holliday, has it in for Joe.
