Dr. Fox just stopped in and evaluated Sarah.  He said the Cirvadil did it's job and as such proceeded to break Sarah's water.  In one barely noticeable movement, Sarah's water was broke and thus the time starts ticking on "Chester's" arrival.  For bacterial reasons there's a 24 hour time frame that the baby needs to come out by.

As a bonus, Sarah, at this point, does not need to be put on Pitocin which is very good to hear.
