I agree. I think Moffat might have made a bit of a mistake for waiting this long to give Clara a major role. Of course she is already the center of the entire plot for this season, she still sadly doesn't get enough attention. Maybe it's some sort of new "ploy" Moffat is trying to use to mix things up. Well, hopefully Clara maintains a more important role as she had in "Journey to the Center of the TARDIS." As for the next episode, with Moffat you really can't tell what to expect. I might love it, I may hate it, but I'll still be watching it. Spoiler: Spoilers the way, who else is hoping Clara remembers the bit from the library? If she does, does it pose a danger to The Doctor?
