Tannhaus had established a business in Winden by 1953. Ulrich Nielsen, having traveled there through the wormhole, sees a young Ines Kahnwald, accompanied by Jana Nielsen, arrive to pick a watch he has repaired for her father.
Tannhaus appeared to have passed away after 2019, as Charlotte Doppler inherits the shop. Since he was the only family she ever knew, she held on to it, and had all the contents carefully preserved. She, Peter, and Elisabeth spend considerable time there trying to learn about how time travel operates.
