I have taken an interest in the moral/ethical implications of this Quest line and it seems there is a lack of information on what happens here in ACT 3.
The quest gives you two Obvious choices:
1) Give the Noblestalk to Derryth she continues to enslave her mentally handicapped husband and you find her in Baldur's Gate. She is not happy but she gives you a discount and is her usual grumpy self.
2) Give the Noblestalk to Baelen which cures his mental fog and he is angry at Derryth for treating him "like a mule" for the last few years.
you can also:
3) Eat the Noblestalk if you are the Durge and unlock memories.
4) Give it to Shadowheart to unlock her memories.
If you choose Option 1:
Derryth is running Bonecloaks, she is as unhappy as ever but gives you a small discount. Baelen is still enslaved.
If you go with Option 2:
Baelen is running the shop and says that "Derryth fled during the night" and he calls her a coward and indicates he resents her for her enslaving him. He gives you a discount and is grateful for your help.
Upstairs you find her diary which seems to indicate she left. Not sure why she left her diary though...

There is also another letter which exists regardless of choice that indicates she made a bad choice a long time ago to marry Baelen instead of another Dwarf named Glumbor. The letter is unfinished and never sent.

Luckily she can be found in the Elfsong Tavern - and she is doing really well.

My conclusion though is that the morally correct choice here is to heal Baelen and NOT give the Noblestalk to Derryth Bonecloak. Baelen may be abusive and mean but Derryth is abusing him as well and enslaving him. Additionally they are caught up in a cycle of what is called co-dependence. Co-dependence is a state of mutual toxicity that prevents both people involved from moving forward, growing and experiencing true joy.
I applaud Larian for this questline, because I think the majority of people fail it and do the wrong thing by giving the Noblestalk to Derryth- it's an example that doing the right thing isn't the easy thing - especially when it comes to relationships like this.
