Amy (Mayim Bialik) isn’t happy — to put it mildly — when she learns Sheldon (Jim Parsons) has told very private details about them to others in "The Allowance Evaporation." The result is their first major argument since starting to cohabitate. After his father (guest star Brian George) cuts him off, Raj (Kunal Nayyar) learns what being financially independent truly means. Johnny Galecki, Kaley Cuoco and Simon Helberg also star.
