The Music Metamorphosis
Summary: Penny and Sheldon's friendship is transforming into something neither of them expected or understand. Each stage of the developing relationship is found in a randomly chosen song that coincidentally – or, in accordance with the law of large numbers - fit perfectly.
Song: "Maria" – West Side Story
"I can't believe you are making me watch this, Penny. Must you insist on torturing me with these insipid romantic movies?"
"Oh, Sheldon, these movies are adorable! How can you not empathize with the fact that Tony has just fallen in love at first sight?" She paused. "Oh, wait. It's you – empathy is a foreign concept."
"Au contraire. I certainly empathize with Tony. In fact, I sympathize."
"What's the difference?"
"I have been in Tony's position. I have felt what he has, albeit under different circumstances – e.g., not during gang wars. And I had known that particular female for quite some time before I felt that instantaneous feeling of admiration."
Her mouth fell open in shock. "What- who -when?"
He just looked at her for a long moment - then turned his attention back to the musical.
