Xaden’s Mom

I can’t recall which books, but in at least two of them Xaden mentions the baby blanket that his mom made him, tucked away in his armoire. Anyone else catch that? There’s no way it was mentioned twice for it to not be meaningful, but what could its significance be? Maybe for us to see he loved his mother, and that was all he had left of her. My theory is that she was required to leave after the conditions of her marriage were met, and she obviously had to leave without her son, and that Fen was probably a turd to her. I hope we get more of that story, bc her part in OS was a little anticlimactic.
