Pietro's eyes narrowed at Magneto, the reference to his sister nothing more than detestable. Did this man not understand that Wanda was his child, not some random mutant for him to portray his crude thoughts upon? It was sickening enough that he spent so much time with Mystique and Xavier, hardly even bothering to keep it a secret from everyone, but for their father to speak to Wanda in such a way told nothing of a paternal affection for his daughter, but more of a lecher going after another prey.
Standing from the bed, Pietro stood before Wanda as if to shield her from Magneto, his head high and proud as if he could deny the very blood inside of him that ran through every vein in that room.
It was true, Pietro and Wanda had come to the Brotherhood of their own volition, but it certainly was not as if they had many choices. Though they were very strong, surviving on their own had become almost impossible and once they had been introduced to Magneto as their father, it seemed that this was their best option. Unfortunately, with that came the blind, naive hope that they could some day be a family. Didn't Magneto at least owe them that much?
"Thank you for reminding us," he spat, no longer bothering to hide his contempt for the old man. "It's such a comfort to know how grateful you are that we give our alliance to you. Regardless of the fact that we're your children." Looking down at the wine bottle in his hand, "We'll be sure to drink a glass in your honor."
