I have two questions, actually

First, what does the "Display information in public profile" checkbox do? Does it enable some kind of event?

And second, I seem to have been locked out of Samantha's route due to a problem I had at a kind of early point of the run, where I got stuck in a conversation loop, don't really remember which one it was, but it kept returning to the same two options, and had to end up picking the one that rejects her, and haven't been able to get any events with her other than the beach and the photograph ones
