How was it winter in Berlin but summer time in New York?
They tried to make Berlin as depressing as possible but kind of over-did it IMO.
shareIT wasn't summer time in New York.. It was winter there too but the sun was shining making it look brighter... Probably metaphorically that he was home, in a free country feeling happy and relieved.
Remember when he was on the train and he looked down on the streets reminiscing about the train journey he had made in Berlin.
The cars in NY appear to be driving along a frosty road.
European cities situated away from the coast can lead to lower temps making it feel colder and more likely of snow fall.
