I really want to see an extension of their B-support where we get the chance to beat up Bernie's father. Something like this:

Dorothea takes Bernadetta into town for some fun (i.e. buying cute clothing) when they are accosted by men who work for House Varley. They are being led by Count Varley, Bernadetta's father, who has had people spying on her for a while. He's rather angry that she would associate herself with a "commoner whore", and wants to punish Bernadetta by harming Dorothea. Fortunately, Byleth shows up with some knights, a fight breaks out, and Dorothea lives up to her word by breaking Count Varley's arm. Count Varley vows revenge, but doesn't get the chance before Edelgard has him placed under house arrest.
