When arriving at Rudolf's hunting residence, the servant welcomes Matthew and Diana with the question "Wie geht dahin?". This is supposed to be German but makes no sense (it roughly translates to "How go there?").
Matthew is told that his bird is called "Sarka" and he explains to Diana that she was a warrior in the Maidens' War. But name is actually spelled with diacritical mark over the 's', meaning it is pronounced "sharka".
