Find two ghosts in the Black Cove. One is Lillian, the other is her father, Nick. Lillian will ask you to keep an eye out for Nick's head.
Get the Talking Head from Reginald in the Southern part of Cyseal (near the circus tents). To get the head without fighting, you must first complete the Warming the Crowd sidequest.
- Convince the head to go back to its body for +1 Altruistic Trait.
- Tell the head it's okay to live out its life as a sideshow prop for +1 Egotistical Trait.
If you convince the head to go back, return to Lillian at the Black Cove and give the head to her. The two ghosts will disappear, leaving behind a reward chest.
