Personally I'd like that too... to happen eventually, but not right away.

It'd be a nice and dramatic touch to have Brandish become Lucy's friend, but reluctantly go back to her own side of the battle-lines due to feeling an obligation to her new home.

Imagine everyone thinking that Brandish turned, but then she sneaks away in night and mist, but Lucy anticipates it (or cames across her by chance) and Brandish says something like that:

"I really like you and consider you my friend, but I have duties and obligations which I can not betray. Sorry, but the next time we see each other, we will be enemies again. But if this war ever ends and we both survive it... I would love to visit you some times and become the friends that our mothers wanted us to be."

Then they embrace and wish each other luck, before going their seperate ways.

Now wouldn't that be an amazing scene?

And it comes with the option of having this sad confrontation on the battlefield, were both don't want to fight each other, but know they have to do it for the sake of their country, continent and other friends.
