BAD BUT OBVIOUS CHOICES.
Fuck Adrien because like hell is he going to kill Adrien I mean come on. He can survive a night of passionate man-on-man action if the other option is never seeing Adrien ever ever again.
Marry Sophie for chaste adoring love fiveever (and possibly preserving the red-headed gene) (possibly not 100% chaste) (probably not 100%).
So, you know. Kill Sade. TWINSIES. \o/
