Penny For Your Thoughts

What I think was going through the minds of Penny and Billy during the course of the musical. Will be a three-shot, maybe slightly AU, depends on how the story goes and what the readers want. I know for sure there will be one-sided Billy/Penny, but if you want, I could make it reciprocated. Anyways, might contain spoilers, or it'll go off, I don't know yet. So, yeah.
