"The Gorilla Dissolution" was moving along like most episodes of The Big Bang Theory with characters dealing with their personal problems. Penny had work trouble, Raj struggled with dating, and Howard was dealing with his mother.

It happened. It really happened and it was perfect. Leonard and Penny are engaged!
