Despite everything about how he perceives time, Jon comes to realize that he falls in love with Angela when she, knowing full well Jon's knowledge of the future is absolute and that he is doomed, decides to fight for him anyway.
The revelation of Philips and Crookshank's origin. They were a kind British couple that he met as a child who helped WWII refugees. He intruded on them during an intimate moment and rather than comply with the general societal and/or social expectations of the time, they take the time to reassure him and help him understand what he witnessed.
