Lisa reviews Emma's schedule with Nico so that he will be prepared for his duties as a babysitter.

Piggeldy and Frederick go to the sea and get into a deep discussion about semantics when Piggeldy tries to describe it.

Lisa's colleague is ill and can't teach her class. Lisa would like to help out, but needs to find someone to babysit for Emma first.

After a good night's sleep and a delicious breakfast, Brigitta's friends want to take her out to see their neighborhood. They hope that they can even convince her to move there.

Frederick gets a bit off topic explaining what a flower is, leaving Piggeldy to draw his own conclusions.

The next potential roommate is obviously too fussy for Lisa's apartment.

After picking her up from the train station, the two roommates are very excited to show Brigitta their apartment. She is impressed, but also very tired from traveling.

Frederick tells Piggeldy about all of the plants that used to grow in local meadows.

The next candidate to take over Nawin's room also fails to make a good impression on the group.

A first potential new housemate comes to look at the room and takes a tour of the group's Wohngemeinschaft (shared apartment).

Julia and Marie have recently moved to Berlin and are waiting for their friend Brigitta to arrive for a visit.

Nico can't stay in the shared apartment anymore, but Lisa gives him some ideas where he might possibly stay.

Nico is disappointed to find out they have the wrong address for his aunt's bike shop.

Frederick and Piggeldy go looking for rainbows, and in the process try to clarify exactly what they are.

Frederick tries to explain to Piggeldy about the spring season, but gets tangled up in references to Chinese food.
