Schotty and the gallery owner get into a discussion about the credibility and value of artworks and artists. We experience two opposing positions, but in the end they somehow seem to find common ground.

In his discussion with the gallery owner, Schotty accepts that one's own opinion can be greatly influenced by that of other people. But he's still very skeptical about how the price of certain works of art are determined.

Schotty pays for his currywurst with a very special five-euro bill, which turns out to be part of an outrageously expensive piece of art from the gallery...

On his new assignment, Schotty meets a young man who has been in a vegetative state for six years, and his caregiver, who explains why Schotty's services are required today.

Schotty heeds the caregiver's advice and tells Matthis stories from his everyday life. Talking about one soccer game of the 2014 World Cup, he gets so excited that he falls...

Schotty, who is claustrophobic at the best of times, wakes up to find himself inside Matthis's head. As he starts to panic, Matthis tries to help calm him down...

Schotty talks to Matthis, who is glad to finally have the opportunity to ask all the questions that have been bothering him since he first found himself trapped inside his own head.

How does Matthis feel about living in a coma? Can he see any upsides to it? An interesting conversation develops between the two men, but Schotty suddenly has to break it off because he has a rather mundane need.

Matthis begins to despair when he notices that the feeling in his eyelid has suddenly gone. Schotty tries to distract him with a story.

With the help of Schotty's narration, the two men turn Matthis's mind into a less frightening and more joyful place. But Schotty slowly realizes that he's not going to be there much longer.
