Continuity mistake: When Cal goes to tell Mr. Dawkins that his daughter has HIV, he brings a glass of water into the room with him. The glass is half full (or half empty, depending on how you look at it), but throughout the scene it keeps switching between half full/half empty and three quarters full/one quarter full.
