Okay, so the attack wasn't that long ago when the bartender told the story. The bartender's son is the guy they saved (or did they?) and the mother and daughter "picking herbs" (probably herbs=bandits) were accompanied by a group of mercenaries, which included the bartender's son.
And then... only Sonia returned (what happened to the mother then? now this makes me curious) and a few of the mercenaries were kept alive, but she either didn't know that or concluded that they must've been killed.
And she is also the marriage partner for the Jun guy.
This is starting to get messy. Real messy.
