“ Oh come on, smile. Lisa, Jack... being bisexual is hardly a crime. Best of both worlds, isn't it?'And Ianto pushed her away. 'No,Gwen. No, really it's bloody not. It's the worst of any world because you don't really belong anywhere, because you are never sure of yourself ot those around you. You can't trust in anyone, their motives or their intentions. And because of that, you have, in a world that likes its shiny labels, no true identity. ”
