Yeah, it would be nice if there was more to the overall Clara mystery - like showing the side effects of what she's done or she might run into another version of herself at some point. And they have definitely brought up the Tardis not liking Clara a lot in this back half of the series, so I would hope that Moffat addresses it at some point. I can see it not being a big enough deal to address in the 50th anniversary or Christmas epi though. I wish we knew how long of a wait it was until Series 8. But I'm sure we'll hear somewhere around Christmas ;)
