Summary
Analysis
Joana takes a moment to consider her kiss with Florian. Did she kiss him to thank him? Or because she really likes him? She thinks ahead to the end of the voyage. It will only take the ship two days to reach Kiel, and then hopefully Joana will be able to reunite with her mother.
Even as Joana makes new connections with her fellow travelers, she continues to be motivated by her desire to reunite with her family. Although she wonders if it was a kiss of thanks, her earlier attraction to Florian suggests that she does genuinely like him.
