I imagine the conversation with teenage-Rachel going like this: "OK, you did X, and I see how that led to Y, and I get to do Z that sounds pretty rad, but, like, dude, WHAT DO WE PUT IN OUR CALZONES???"

One of the awesome things about writing stuff like this down is being able to come back to it in the future and see what things are most surprising. I suspect our sixty-selves will be even more awesome.
