Why, yes, I am very happy with this outcome.
(God, Jesus Christ, I've been meaning to post something like this image ever since we started the game, fuck this feels so good.)
And yes, you can only pick one of the boys. It's either Themba, Wolf or Khenbish. But if you pick Arts as your background you can pick two (one with Jean, another one later by adding a decoration to the reception.)
...That said, if you pick Leader you'll be able to recruit two characters in Build 0.6, when otherwise you would only recruit one. So that's another neat bonus.
Ah, what a conundrum, eh?
