I can totally imagine Prussia losing Germany and him going up to a poor person and asking:

"Hallo, have jou seen mein baby bruder? He has blonde hair, blue eyes and answers to the name 'Ludwing'"

And so the person agrees to help find him expecting a young child. But then a tall muscular Germany appears through the crowd and Prussia running up to him like:

"OH MEIN GOTT VHERE WERE YOU?! I MISSED JOU SO MUCH! NEVER DO ZHAT AGAIN!"

And the person is like:

"wtf...?"
