Happy birthday Prussia! And yes, it was necessary for the story, because it brings out the angst~!
And also, headcanon that exchange for Gil to call Matthew 'Birdie', he gets to call Gil 'Pooh bear' or 'bear'. Reason why? Gilbert and Whinny the Pooh's birthday is today as well.
HAPPY BIRTHDAY POOH BEAR.
