As John and Kathy look out over the New York Skyline from the River Café, the new World Trade Centre 7 and Beekman Tower can be seen, both of which didn't exist before the events of 9/11 and were built in 2006 and 2011, respectively.
At the very end, John walks up from street level into the plaza and as the camera continues to tilt, it shows that he is walking from Tower 1 to Tower 2 with The Marriot in the middle.
This journey is impossible as the actual street level entrance to the plaza was from Church Steet and up between Trade Centre 4 and 5, where as the journey he takes would place him on Vesey Street which was above ground level but was also where Trade Centre 6 stood as well as the bridge connecting the Plaza to Trade Centre 7.
