Astoria
It seems as though tying a daughter to someone so willing to burn the world is a dangerous political choice. His reputation is becoming more and more tarnished by each passing month, and I'm curious at how many empty bottles and failed engagements it will take for them to finally make Cygnus their true heir. If he wants to be that self-destructive, let him do it on his own without harming the reputation or legacy of House Lestrange.
It is unfortunate that they have to spend so much time babysitting this man-child.
