But if we're starting on What If's. I bought an earlier draft of an episode and in that one, Sara was so intrigued by Michael, that she went to his old apartment and bought the old stuff which was still there, from his landlord. Between his sweaters she found her yearbook, with her picture marked. I would have found it interesting to see how she would reacted to that on the show. Especially since it was pretty early in the first season.
