Things are getting more interesting. This episode focuses on 1986 as this is when Mikkel has ended up. As we learn, 33 years ago strange things were happening in Winden too. Dead birds falling from the sky, power switching on and off, 33 sheep dying in the same way the boy from 1986. How much chance is there that any of this is related to the nuclear power plant, especially as it's mismanaged?
Mikkel is isolated in 1986, unable to tell anyone the truth without them disbelieving him. When he tries to communicate with 2019, his father can almost hear him but they can't reach each other. Time travel also gives us a chance to see characters how they were then. The most striking change is Ulrich. By the type of person he was in 1986, you wouldn't have thought he'd ever be a police officer, as one comments.
As Mikkel explores the Winden of the past, you start to see how characters became what they are now. Older Hannah's affair with Ulrich makes more sense now, and older Charlotte's suspicion that history is repeating itself is supported by her memory of finding dead birds in 1986.
There is some stunning cinematography, the aerial view of the dead sheep being particularly creepy. The scene in which birds fall from the sky is also wonderfully eerie. The side-by-side of the same characters from 1986 and 2019 is both helpful and effective, especially with a fitting song. And the scene with Mikkel and Ulrich in the cave is quite interesting, I noticed Ulrich heard Mikkel's voice not from the other side of the door but from behind him. I guess this is because Mikkel *is* behind Ulrich, not in front of him, only in a different time.
It's not all quite perfect; there is still some heavy-handedness in the script, with a character stressing that 33 sheep are dead, when in reality you wouldn't care whether it was 33 or 34, the line is clearly just spoken to draw attention to the number 33. In fact it would be more interesting if the number went unsaid, allow the eagle-eyed to notice that there are 33 sheep in the aerial shot. Aside from some minor quibbles, it's a very good episode.
