Actually come to think of it, you' could be right- that material probably could have bene added somewhere in the developmental section. I added it at the last minute because I thought it was a good transition from the A theme to the B theme- Both themes are very harmonically stable, and I assumed that a transition between the two should be a little more....unstable.
I don't have a PDF score, but I'd be glad to send you the score in .jpg form if you'd like.
