First Companion to actually threaten the Doctor
The Doctor: She'll be fine.
Clara:Speak for me again, and I'll detach something from you.
< long beat> I'll be fine.
Definitely a new dynamic ever since Clara came on board. Even the Matt Smith Dr was suspicious of her because she was the impossible girl who kept turning up through history.
In last nights episode Missy did mention the fact that there had been time ladies but I think she’s an incarnation of the master.
I think Clara is on the way out. Probably.
