Paula and Philipp have solved the mystery of the crop circles, but they're still not sure if UFOs exist or not. And what does U-F-O mean anyway? Eulalia insists that she has seen one. Finally, the journalists ask the guests in a village pub what they think about the fake crop circles.
The pub visit is a good opportunity to introduce the past tense, especially with the irregular verb "sein" (to be). The modal verb "können" (to be able to) is also reviewed in this episode. Pay close attention to vowel changes when conjugating the verb.
