Still in Houston, Sheldon and Howard drop in on Sheldon's mother to surprise her and Sheldon sees her having coitus in the living room. Later he returns to discuss what he saw, he gets indignant and Mary Cooper sends him to his room. After Howard tells him about how he drove away an admirer of his mother and she is still very lonely, Sheldon apologizes telling his mother that he will accept her choices on the outside while condemning her internally for being a hypocrite by going against her religious beliefs. Her mother is fine with this arrangement and forgives him. Sheldon then starts lecturing her on safe sex much to her discomfort.
The rest of the gang gets roped into a murder mystery dinner arranged by Raj. Stuart comes in and supposedly dies after eating something. After finding a future receipt for a coffee, they travel to the future with future lives supplied by Raj.
