Something is just bugging me. Once upon a time, When Donna traveled with the Doctor, she had to have her mind completely wiped of any knowledge of him else she would burn. In this episode, Clara sees "The history of the time war" book and apparently reads the Doctor's true name which NO ONE [except River] in the universe knows and she just shrugs her shoulders. Like it's a completely none event. Like it's Doctor Bob. Yet when she see's the Doctor, and tells him she read it, he's like, it must never be spoken. Just doesn't make sense.
