The plot of the game (Dragon's Dogma)

The game constantly surprised by) After killing the Griffin he met the servant of the wife of the Duke, she asked the night to meet her owner was found, they put me in jail. The task to get out - go anywhere all guards do not care, okay, then return to the castle as if nothing had happened, though like all should already be aware of. And here's the question - is this all normal or is it a bug or I somewhere blunted? Well, not seen in any RPG such ridiculous plot moves, so to speak. The Japanese, I understand, but not as stupid.
