The Doctor Who team at the BBC has released a series of videos to preview the final episode of Amy and Rory. Once again Steven Moffat promises a tearjerker where not everyone gets out alive.

The first video sets up the 1938 timeline in New York. Of note are two things that are likely a case of unintended anachronisms.

In 1938, unlike today, there weren’t apartment buildings near Battery Park. Battery Park is the southern most park on the tip of Manhattan Island, and was a former military defense post in the 18th and 19th centuries. From Battery Park you have an excellent view of the Statue of Liberty. Apartment buildings in that area that exist today were built on reclaimed land projects done post-WWII. They did not exist in 1938. That section of the city has been a financial one for decades. Up until the late 20th century, it was a veritable ghost town after 5:00 p.m. and weekends when the Wall Street trading day was over. In fact, housing in the style shown in the video has never existed in the Battery Park area. You would have to go more north to find that style.

The second item of note is the phrase “Winter Quay” appearing in neon lights atop an apartment block. Though the word “quay” is in regular use in the U.K., it is not a term used at all in the United States. Quay essentially means “pier,” and for over a century New York City has numbered its piers and alternatively referred to them by a specific name, such as Chelsea Piers and the South Street Seaport (Pier 17). They are never, however, referred to as “quays.”

Next up meet the cherub angels and River Song is back.

Lastly, Matt Smith, Karen Gillan, and Arthur Darvill introduce the Ponds’ final episode with additional commentary by Caro Skinner and Steven Moffatt. Moffat repeats his warning that not everyone gets out alive, and in fact he made his son cry.

How emotional do you think the end of the Ponds will be compared to the Rose Tyler and Donna Noble departures?
