“You never talk about it?” That's surprising to Wolfgang, but then, they gather their relationship with their family is much better than Michael's. Sure, Wolfgang's the one who fucked off without a word in the middle of the night as a teenager and let their family believe they were dead, but before that, they were close, even if they have to reexamine that relationship in light of what they know now, about their parents concealing their power from them. They heard a lot of stories. A lot of the same stories over and over. (“I remember a time in the Old Country —” “Yes, grandpa, we know.”)
The idea of having family right there across the table from you and never really speaking to them is inconceivable to Wolfgang. They never really thought about it before and now it makes their heart hurt.
