During the period in Amsterdam it wasn't totally clear whether the next stop would be Hamburg or Berlin.
Coming into Amsterdam Dave & Kate had been feeling Hamburg was next and this seemed confirmed by the freight train they passed as they arrived at Amsterdam Central with 'Hamburg' painted on the side. They seemed to know they had to go there at some point for whatever reason.
Just as with Amsterdam they hadn't overly fond memories of Hamburg and their impression of it was a gritty, northern port town not too dissimilar to Glasgow. It was also approaching December and getting colder.
They had also been in touch with Mark and Brian around this time with the possibility of meeting up somewhere in Germany. Berlin seemed the most likely place.
Berlin was growing and seemed to represent the Heart. If the land of Europe was a physical body (maybe it is?) then Berlin was the Heart. They knew they were on their way but didn't expect it to be so soon.
It looked likely a meeting with solo Mark was on the cards but it wasn't to be for now and a decision had to be made and so Hamburg it was. For 3 nights. A train ticket for Berlin after that was also bought.
After the laziness and comfort of Amsterdam, they were ready for going back onto the battlefield...
