Some of it. The Veil was... less than kind to me when I arrived here. [And Emma didn't exactly go into lurid fanfic detail about her parents.]

But he was married once. It had a few difficulties, brought on by him falling in love with another woman- one who is sadly not here with us. Apparently, the Veil saw fit to take his memories of both women, though perhaps it couldn't sever the feelings entirely. Your curse is terrible, my dear, but imagine loving someone you don't even remember.
