A string wall with photos of several people from Winden was located in a cellar. There were different photos of the same people from 1953, 1986 and 2019. Relatives were connected by string, as a sort of family tree.

It is seen in the future/alternate reality of the bunker in what is presumed to be the next leap ahead after 2019, which if 33 years later would be 2052.

The red string moves from Mikkel/Michael in ("Secrets") to Jonas/The Stranger in ("Alpha and Omega").
