Why do Jan and Bob become so important to Chris/Alex?

Jan becomes emotionally attracted to Chris, while Alex loves Jan. Chris and Bob are in a secret relationship (don't judge) that they want no one to realize. After Jan confesses to Chris and is rejected, Jan spends the next 2 years of her life investigating Chris, eventually coming to the conclusion that Bob is Chris' sweetheart (again, don't judge). Jan invites Bob on a vacation to Greece, planning to murder Bob to possibly become Chris'. However, on the flight to Greece, the airplane crashes into the Ocean, more than 50 miles from any major piece of land. Backtracking slightly, as we have yet to mention Alex's role. Alex discovers of Jan and Bob's vacation, and misunderstands, believing THEY are the ones who love each other. Alex secretly boards the same flight as the two, and midair, kills the pilot and purposely crashes the plane into the ocean. There were no survivors on the trip, much to Chris' distraught upon his discovery.
