Why would Granger drag Blaise with her and risk not being able to bring him back to Ginny when there is another solution? She knows I'll do whatever it takes to stay alive, but if I fail, it's indeed no great loss to the rebels. Especially now that I have already shared and recorded so much information. There is nobody who would shed a tear if I didn't return to Camp Black; nobody who would be devastated if they lost me. The only person who cares about me is still convinced that I'm already dead. And even if she knew that I'm still alive: my mother is not yet a member of the Resistance. So no, nobody will miss me here.
