At Roosevelt hospital, Jamie requests that Paul return home and retrieve Jamie's ring. Paul estimates that he could be back in 20 mintues, implying 10 minutes each way. Not in New York City. Even if the Buchmans lived next door to the hospital, merely leaving a 1000+ bed hospital, and negotiating the Buchman high-rise would require more than 10 minutes.
(Hoping to induce labor, Paul makes amorous gestures toward Jamie, who will give birth imminently)
Jamie: If I was falling out of a plane, I'd be more in the mood to do this than I am right now.
Paul: What do you mean? This is not it?
Joan: Nope, not it. Often mistaken for it, but not it.
Jamie: You sure this isn't it?
Joan: Yup, false 'it.' Take my word for it. That's my job, distinguishing actual 'it' from not 'it'!
