Rat pie

Hello B)
I am having a problem with the stout brothers and the rat pie quest.
I've handed over the pie and headed back to the first brother for my reward,... the secret.
Problem is I've tried every dialogue option there is in the list even vaguely concerning the pie and its delivery to the other brother and... nuthin. no secret, no new dialogue.
Whats the go?
this is my first post here so how bout a hand eh?

I don't think you ever get anything from the first brother, except how to enter the crypt...just find out from the second brother how to advance in the crypt...

After promising to deliver the pie he already tells you the secret: how to get into the crypt (as if you couldn't find that out for yourself). Be warned: most NPCs outside the cities don't register that you have done their quest, and you won't be able to tell them, even though they ask about it!

After giving the ratpie, he well tell you a secret about F'Lokis Ra and about the elevator (I think).
To be fair to the game, though, I've never had any problems with NPCs outside cities and the quest connected to them. Just lucky I guess.
