Most people are probably drawing that from the intro [S] for act 6. But, like someone else said, was probably from Jane's current time.
This also explains a lot. Like how Roxy just happened to know so much about Troll culture. She being from a (supposed) Human colony is probably bombarded with it. And maybe why Dirk likes Jake, probably he feels a connection with him because they both live alone (Jake much longer than Dirk.)
