On this page Eric tells Jen about the Santorini Man.

May, 1936, Santorini. Body had no ID, no fingerprints, no possessions besides his clothes + a torn page from Braxenholm.

Goodreads user Lindsey1980 suggests that the Santorini Man case could be related to the mystery of the Somerton Man. According to Wikipedia, a man was “found dead in December 1948 on the coast of Somerton Beach, Glenelg, in South Australia with a scrap of paper with the words táman shud, which means ‘finished’ in Persian, in a hidden pocket in the man’s trousers. The man’s fingerprints were not in South Australian police records. By November 1953 the police had received 251 ‘solutions’ to the identity of the body. The police said that the only clue of any value is the clothing the man was wearing”

The notes on the page, besides Eric’s reference to the Santorini Man, have nothing to do with what is on the Actual page of Ship of Theseus. S. is still trying to make sense of what is going in this place and why people are protesting in front of a factory while trying not to be seen. Meanwhile, Jen and Eric talk about Ilsa:

She only pays attention to people who can help her advance.

(…)

You had a thing for Ilsa?

You’ve already decided that.

So I’m right.

Yes, you’re right. Does that bother you?

Of course not.It’s kind of reassuring to know you’re capable of actually interacting with people.

This conversation shows the interest in both sides. Jen wants to know what happened between Eric and Ilsa and Eric wants to know if the fact that something happened between them bothers Jen.
