I think Harry is very loyal to his friends, and is also well aware of the media circus that follows his every move, and will want to keep his personal life as private as possible. Regardless of when or why he was there, he has (inadvertently) given photographers permission to camp outside of Chelsy's doorstep (as he did when speculation was high about he and Flee). Chelsy -as far as Im concerned- has been dating others since Harry, and working hard at her chosen career. When she returns to London it'll be interesting to see how she copes, as she had faded to the background in recent months. I hope they both continue to grow as individuals. I read a quote somewhere that the person you spend your life with should make you want to be a better person. I hope these two find that!
