Wayward Son

 is a side quest in Torment: Tides of Numenera.

Synopsis
Mother Temaz, an old midwife in Cliff's Edge, asked me to assist one of her wayward "children," a young man named Piquo who is struggling with a difficult choice. If I can help Piquo make his decision, Temaz will return a piece of my caul to me, fashioned into something valuable.

Walkthrough

 * Head to the Chiurgical Parlor and talk to Piquo. He'll explain that he has enough money to pay for one operation and can become either big and ugly or small and attractive.
 * You can inquire about his situation and use (Persuasion) to learn more about him. It turns out that he comes from a pitiful tribe living in the Underbelly. Hideous from birth, he left it when his father was killed in a bar. And so, ever since he was 12 years old, he was on his own.
 * You can decide between these two options... Or with more (Persuasion), convince him to get himself an education at the Order of Truth or indulge himself, wasting that money. If you have Tybir, well, he'll want to fleece the lad, ending the quest. Alternatively once you have discovered Piquo s past, you can talk to Crooked Qeek in the underbelly and ask her about  Piquo. Then return to Piquo and using either persuasion or intimidation to convince him to return to the Underbelly to look after her.
 * Return to Mother Temaz.
