... I'm ashamed to say I didn't even consider that meaning of his name until right now when I saw your picture! I can't believe I read 600,000 words of a story who's main characters are "BlackJack" and "21" and never realized their names referred to the same card game... I'm aghast at my own lack of comprehension... did I even understand anything that happened in that whole story???
After rereading a few chapters,I guess I can consider the armor being the beat up one before she gets her replacement one. p.s:my previous comment was just a joke. A rather unfunny one since you took it seriously
