I think Riley is the best CSI on the show right now. Don't get me wrong sarah was awsome and Warrick was cool(Nick,kathrine,greg,grissom and others are good to). I just love how she has a dark past and is kinda mysterious. She has a quirky aide but also a serious calm side. She can get herself out of difficult situations by being calm( episode No Way Out). She took control and talked her and Ray out of it. Ya she's a little trigger happy but that makes her, her. I think her and greg would be adorable together. But i think they should show more of her so we understand her better.
