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.

Nico comes by after Lisa is finished teaching. While Lisa is on the phone with a potential new housemate, Nico takes a look around the room.

Lisa teaches her students the importance of learning nouns along with their articles so that the gender gets memorized as well.

Piggeldy and Frederick venture out into the snow to look for signs of other animals.

Lisa is in a rush the next morning, but promises Nico that they will go see his aunt after she is finished with work.
