Just a small thing, but it always bothered me how Ding Jian (and some other guy Shi something) dropped their swords completely and became servants at the Plum Manor for the 4 Lords because they saved their lives. Why the heck would someone to that? I'd of course be extremely grateful and treat you as my benefactor, but to come to the decision to be an obedient servant for the rest of your life? It is especially weird since they were originally shady, dubious fellows to begin with.
Also a bit weird that the 4 Lords decided to join the Sun-Moon Sect of all places because they had an urge to do heroics and uphold chivalry. Did that sect ever have a good/non heretical reputation, like the Ming sect originally did?
What other small details irk you guys?
