witcher

Father Knows Worst is a secondary quest in the Blood and Wine expansion.

Armed Escort Wanted!
We wish to hire a person (or persons) with good weapon skills who, for a reasonable fee, will escort us into Albertus Cavern for exploratory purposes. The knights errant claim the cave harbors no dangers, so we don't expect trouble, but better safe than sorry.
Auguste, Lucien and Hugo Monnart

Walkthrough

The easiest way to start this quest is to find the contract notice on The Gran'place's notice board, but you may also stumble upon the Albertus Grotto, north of Rioux-Cannes Outpost. Regardless, once you enter the cave two brothers, Lucien Monnart and Auguste Monnart, will be screaming for help and ask Geralt to save their 3rd brother, Hugo Monnart. You can haggle if you wish, then enter the cave after agreeing to help.

Inside, Geralt will be attacked by quite a few Kikimores (many workers and a lone warrior). They can poison in such a way that it rapidly raises Toxicity, preventing you from using potions unless White Honey is used to clear it. Thus, it's a good idea to imbibe your potions before entering the fight. However, this can also be a good thing if you have Euphoria or Toxic Blood. After disposing of them keep moving and you will soon find a sword and a trail of blood, so follow it to find Hugo (don't enter the hot waters you see on the way). He will mistake Geralt for an assassin his brothers hired to kill him. It turns out they wanted to exclude Hugo from the liquor business they were meant to inherit evenly from their father, who split his condenser into 3 parts, 1 per son and this cave is where Hugo's part is located. He will then ask Geralt to search for it and you can agree or refuse.

The missing part

Note: If you at any point try to exit the cave and talk to the brothers, Hugo will instead find you at the exit and you'll be missing on this part of the quest and the reward for it.

Go back to the previous cave where a hot water spring is, and Geralt will comment that Quen may protect him, which does indeed work. However, as its duration can run out it's also a good idea to use your Witcher Senses beforehand and find a spot to drop near the red-glowing item. Dive in and get the Still filter.

You can also take a detour to a corridor nearby where you will have to fight more kikimores for access to an Axii Place of power. Nearby is also a female body, on which you can find a letter detailing the story of the missing part.

Regardless, return to Hugo with the filter in hand and he will reward you with 100 Oren3. (150XP earned based on the Story and Swords! difficulty level)

Important: Finding the filter will count as "Proof of Honor" for There Can Be Only One. However, it only seems to work if you find it after talking to Hugo and not before.

Happy Reunion?

As you reach the exit, Lucien and Auguste are waiting with some thugs and Hugo will ask Geralt to kill them as they are probably there to kill him.

If you agree, you will have to fight them, though it will be pretty clear something isn't right. After they are dealt with (the two brothers don't actually die), Hugo will thank you, and if asked, says that he'll probably leave the business and Toussaint altogether. (150XP earned based on the Story and Swords! difficulty level, but no coin)

Important: Hugo as a merchant will buy anything including decoctions/potions. He will also pay more than any other merchant, although he has only 600Oren3 of buying capital. Selling him decoctions is worthwhile for a Metamorphosis build, as you may also buy them back as opposed to just destroying them.

If you say no one dies, it turns out that the thugs are just some hunters who came to help from a nearby camp, and the three brothers will decide to "bury the hatchet". If you didn't get the filter, they'll say they found it themselves while Geralt was looking for Hugo. They then pay the agreed amount of coin (300 Oren3 by default) and invite you to visit them at The Clever Clogs Tavern. (150XP earned based on the Story and Swords! difficulty level)

Important: Refusing to fight the brothers will count as "Proof of Wisdom" for There Can Be Only One.

Journal entry

If Geralt finds the contract on the notice board first:
One day, while strolling through Beauclair's bustling streets, Geralt spotted a notice - someone was in need off [sic] an escort as they wished to penetrate a cave. The task seemed none too complicated or taxing, so the witcher concluded it would be unwise to let it pass.
Before speaking to the posters of the notice, Geralt set out to do a bit of reconnaissance. Yet he returned to them quickly to find out what the job was to entail. The brothers, trembling in fear, explained that their other brother, beset by monsters, was trapped in a nearby cave.
If Geralt happens upon the brothers in the cave first:
One day, while traversing Toussaint's charming wilderness, Geralt ran into two men desperately calling for help. As they told it, their brother had remained in the cave they had just hastily left. Nothing out of the ordinary, I suppose, if not for the fact that inside this sibling had been attacked by beasts. Geralt decided he would try to help the man.
Geralt followed a trail of blood to find Hugo. Wounded by monsters, the man had sought shelter in the cave's depths.
If Geralt didn't already find the condenser and agrees to help:
Hugo begged Geralt to find a condenser, part of a complicated contraption his father had devised. Papa had cast this part into an underground lake.
As Geralt and Hugo were leaving the non-too-hospitable caverns, Hugo's two siblings, assisted by a handful of armed men, blocked their way. Fearing for his life, Hugo begged the witcher to teach his treacherous bastard brothers a lesson.
If Geralt says no one dies today:
Yet as we all know, Geralt has a strong aversion for unnecessary violence, so he turned Hugo down. This proved a wise decision - forced to discuss their differences, the three brothers settled their dispute and resolved to embark on an enterprise together.
If Geralt agrees to attack the brothers:
Deciding that he should see the matter through to the end, Geralt fulfilled Hugo's wish.
