Marvin translated Bismarck's words into Windsor, and Archbishop Brandon was momentarily stunned, then remembered that Marvin was from Frederick, and his journey to the Kingdom of Windsor to join the Church of the Three Goddesses of Fate was already tantamount to 'treason'.
As Chancellor of The Empire, Bismarck wouldn't have a pleasant expression upon seeing Marvin, it should be said that it was already quite difficult for him to sit down calmly for a discussion.

Archbishop Brandon found himself in a dilemma, from his perspective, seeking the aid of the Frederick Kingdom Delegation would definitely require resolving the 'conflict' between Marvin and Bismarck first.
After some thought, Archbishop Brandon still couldn't find a good reason and decided to phrase it differently, "Chancellor Bismarck, we have encountered a problem, and this problem is also related to your country."
