They showed The Doctor's past from the point of view of The Doctor at that point, but she went into his time stream from his grave (i.e. his complete and total time stream). Thus, she went into all of his time, they just haven't shown any of the future time into which she went because we are working from the point of view of The Doctor from where he is currently in his time stream.

Bad wolf was mentioned in multiple episodes, but only in passing. Torchwood was the same, as was vote for Saxon. They were ongoing things in the background that eventually made sense, they weren't the entire storyline for the main companion that was constantly referenced. The Doctor has called her his 'impossible girl' on multiple occasions, so much so what does it mean anymore? Even she should perhaps have questioned it more than she did. Plus, her role as slightly smug and in charge mirrored virtually completely River Song, who herself became incredibly annoying well before she was got rid of.

As far as I understand it, the two sides of it are:

- The real Clara has a vague awareness of what her past lives did but not to any great extent. She needed help recognising Ten in Day of the Doctor.

- The echoes of Clara seem to have some sort of awareness right before they die. Oswin in particular seemed to know during her final moment on screen from the way she smiled at the camera, and Victorian Clara repeated her line.

So other than some vague telepathy-type stuff, I think that's all there is to it.

The whole story was so under-cooked though. The idea that Asylum was the first time he had EVER noticed her, not to mention the absence of the Great Intelligence in that story, were two big problems I had. Not to mention that somehow throughout his investigation of Clara, the Doctor never once found multiple Earth-based incarnations listed even though Artie and Angie managed it in one afternoon.

I'm not so sure that either of them had any awareness of what was happening - and the glances to camera and repeated lines were more for the audience's benefit than the characters'.


But, yes, there seem to be certain memories of the original Clara that persisted in the 'echoes'.
