At the end of "The Reality War," Belinda tells the Doctor that Poppy's father is her ex-boyfriend, Ritchie Akingbola. The Doctor confirms Poppy is 100% human, but <em>Doctor Who </em>doesn't imply that she is no longer his daughter, either, so I'm a bit confused. I'm wondering if Ritchie is a human alter ego of the Doctor's, like John Smith, and the memory of him has been blurred in Belinda's mind, so she doesn't realize they're the same person. I really hope Russell T Davies eventually clarifies this, but I have a feeling he won't.
