Well, the earlier mentioned Lieselotte certainly proves you can have a successful arranged marriage with your very gay husband, and it's true, Amelia wouldn't have been cast as "the woman Dad forced me to marry". Also, the Countess Orzelska proves he could pull off het romance at least once. Assuming the marriage would not have been a catastrophe and went as well as it could under the circumstances, do you think it would have changed anything in terms of alliances? For example, would G2 have been a bit more supportive in the 7-years-war, or would Fritz have helped out nephew G3 in the colonies later?
