S4·E4 Grandpa's Secret Life

An old Polish man finds Grandpa and forces him to marry his daughter. He finds out that Grandpa was the man that came over on the steamship Krakaur in the early 1900's, and that he and his daughter did the hanky panky together. When Nell meets the man's daughter, she tells her that she doesn't care about Stanely, and that she is afraid of her father. When Nell brings her to the house, she finally faces up to her father, tells him she doesn't want to marry Stanely, and says she is in love with an Italian man.
