After the winter sun rises over Prague, Robert Langdon sits with lingering anxiety about a final loose end he must resolve before he and Katherine Solomon fly out that afternoon. He regrets not yet explaining the “delicate situation” to Katherine, especially after a tense farewell with Sasha Vesna and final discussions with Ambassador Heide Nagel.

Langdon and Katherine eat Nagel-recommended “prosecco breakfast” at the Alchymist Hotel, watching the courtyard ice rink. A young woman in an ornate skating outfit stumbles onto the ice and starts taking selfies, prompting Langdon and Katherine to joke that she is an “Instagram skater,” not the hotel’s rumored ghostly nun.

The moment leads into a serious conversation: Langdon worries about people living online, but Katherine argues the online world is real in its own way and uniquely “nonlocal.” Katherine frames internet immersion as a bodiless, out-of-body-like experience and a possible training ground for humanity’s spiritual evolution, reinforcing her core conviction that death is not the end and that this belief could transform the future if shared widely.

When Langdon urges her again to publish her book, Katherine’s mood dims, reflecting her anger at the CIA and the daunting task of rewriting. They decide to go see Prague Castle, and Katherine notes she lost her bag; Langdon reveals breakfast is covered by the U.S. embassy, which also promised to deliver travel cash, first-class tickets, and diplomatic letters to smooth their return.

On the uphill walk toward the castle, Langdon abruptly stops, checks his watch, and tells Katherine he has paperwork to handle before he can leave the country—an unresolved matter from the chaotic prior day. He insists she continue without him, promising he will catch up, and proposes they meet at “the door with the seven locks,” leaving Katherine unsettled but moving on.
