Darkness Before Dawn significant moment

So far in my book the significant moment has been when Keisha and her friend were at the library. They saw Jonathan Hathaway who was trying to talk to Keisha offering to help her in her SAT preparation and insisted in helping her with anything she needed. Jonathon Hathaway is a junior at the university, majoring in education. He started doing his student observation and had volunteered to help coach some of their basketball and track teams. So all the students called him Mr. Hathaway but he told Keisha to call him Jonathan.I think that that is the significant moment so far because Jonathan is starting to act a certain way that makes Keisha uncomfortable.
