When Nico shows Nina and Sebastian the photo of his aunt, Sebastian has the idea to post the photo online and see if anyone recognizes the bicycle shop.

Nico goes to the "Wohngemeinschaft" ("WG") where Lisa lives and meets her housemates, who are getting ready for a party.

Nico and Lisa go to the police station, where her father files the little information Nico can give him.

Nico has the bold idea to call a radio station and tell them about his missing bag.

While Lisa drops Emma off at a birthday party, Nico waits in the car and hears something interesting on the radio.

Nico and Emma play a game in the car just before Lisa drops her off at a birthday party.

Barbara and her students look at a few more sentences that each have a nominative subject and a dative object.

Lisa calls her father, a policeman, to see if he can help find Nico's aunt.

Barbara takes her students through some verbs with complicated structures, such as "fehlen" and "gehören." Luckily, Macy and Cramer are able to act out some of these to help their fellow students.

Nico, Lisa, and Emma run into Lisa's friend Max, who suggests that they get Lisa's father to help with Nico's situation.

In the second video about the third category of verbs, Barbara takes the class through verbs such as danken and passen, which require the nominative and the dative.

Barbara introduces sentences that only include the nominative and dative, particularly sentences with the verbs gefallen and schmecken.

Nico thinks he has maybe found his bag, but no such luck.

Nico learns how to tell Emma and Lisa his name in German. When they stop to put gas in the car, he sees something he recognizes.

Nico still doesn't have his luggage, and can't exactly remember his aunt's address. Lisa and Emma offer to give him a ride into the city.
