WHAT?!
Why Moonbox would do that? It's totally not in character of what he does. I mean, even with Natalia, he never showed something like that, it was only said but at least it serves a purpose in the game. Not in that case tho.
Brandi is probably only a one-shot deal, never to be seen again OR to be seen one last time. Also, looks like Brandi's soon to be divorced, so, another reason I don't see that happening.
It would be one of the weirdest and worst things to do to bring back Brandi.
I still hope we'll see Brandi one last time. Maybe she joined the Church of El Pene Del Diablo?
