"Brilliant Sheldon is confronted by a mystery of the universe he cannot unravel: when a woman wants time apart to think, exactly how much time does that mean, and is there any way to hurry the process along? In Las Vegas, Penny and Leonard march closer to marching down the aisle, but has Penny gotten over Leonard’s infidelity? And if so, will he do anything to un-get her over it?"
Leonard and Penny get married but Penny is not happy to learn he is still working with the woman he kissed while on the north sea exhibition.
Sheldon pushes Amy over how long she needs to think and she breaks up with him.
Sheldon uses his classic "Knock, knock, knock Penny" to bring Penny tea. We are calling this The Shenny Tea Party (well, I am, probably no one else.)
