Quote from Sophia in End of the Curse
Dorothy: Blanche, who's the father? Blanche: The father? Gee, I don't know. Dorothy: Well, you'd better figure it out. When was your fertile period? Blanche: I'm nine weeks late, it would have been two weeks before, so 11 weeks ago. Dorothy: Nine weeks late and you just realized that something is wrong? Blanche: Yes. I kinda lost track. Dorothy: Well, I think you better get out your book and find out what you did that week. Sophia: We know what she did. We don't know with who.
