* Baley and Daneel's reunion is pretty touching, partly because it shows how far Baley has come in his appreciation of Daneel. In ''Literafure/TheNakedSun'' when he met Daneel again he felt the urge to give him a hug but resisted it because after all, Daneel wasn't ''really'' an old friend, just a machine. In this book, however, Elijah is very open about the fact that he ''does'' consider Daneel a friend, and the first thing he does when meeting Daneel again is to go up to him and hug him.
