I feel like one of these film makers that, god, Swedish guy's name, because ideally to rate my own stories I'd give you a list of the characters and would not indicate if they are / or , simply because the boundary between the two is so thin sometimes, when does the , grow into a /? I think it's easy to classify PWPs but as soon as you have something ther than a PWP I feel the / is whittling it down to a over-simplified description that doesn't do a story justice. If Jack and Ianto interact on the background of their relationship without interacting in terms of a relationship is that /?
