It has only been about 20 episodes since we last saw Franz von Sickingen. Out of all the livery he has swapped out to show his allegiance to Loyola, I can only imagine that finding the type of silly hat he wears in red was the trickiest bit.
Of course, since silly hats play a big role in our decisions of who to include in the comic it is probably good that he went to the trouble.
