Private
No apologies are necessary, I don't know what Grindelwald did while masquerading as myself, and I shudder to imagine. All the years of work I spent and my reputation is most likely in tatters. People probably think I'm dead at home, and to be honest I prefer it that way. Rather that than have people suspect that I'm in league with him.
Scamander, you say? You're Theseus's brother, right? We fought together in the war, he always spoke very fondly of you.
It's good to meet you, though, and even though I personally didn't have a hand in it, I apologise for what you and your friends must have gone through. While I'm morbidly curious as to what happened while I was locked away, I know I'll most likely regret the answers I receive.
