About the ending in the first episode (Spoiler warning)
In the very last scene of the first part, when Johannes and his ex-girlfriend have found their ways back to each other and happily and in love drives away to their new life together, the viewer suddenly sees how the car starts going slower and slower and how Johannes is seen sitting all stiff in front of the wheel?
Sarah, sitting beside him in the car, notice this and says "Johannes?, Johannes?", looking at him with a puzzled expression on her face but without him giving any responsce but continuing to just sit all stiff while the car goes slower and slower and eventually stops. Then, Sarah looks terrified at him, loosens her seatbelt and rushes out of the car over to his side - And right then the movie ends.
What happened? Did he die or something?
At first I figured that maybe he changed his mind and instead wanted to go back to that other girl, what her name were again, but the whole scene was so odd in that he just sat there all stiff without any reaction what so ever and she rushing over to his side locking panicked, plus, they just moments earlier being so obviously back together and in love.
Perhaps an explanation was given in the second episode? I only watched the first and the third, so maybe I missed it?
