Sorry to go a bit off-topic, but it's also on the topic of Clara. Wikipedia says about the next episode: "This episode will be seen from Vastra, Jenny and Strax's point of view as they encounter the Doctor on one of their cases."
Does anyone know how much of the main duo will be in the episode? It sounds potentially a doctor-lite.
I'm feeling this mind-wipe we got to experience a bit better what keeps happening to the Doctor. It's feels like a uber-mild version of what happened to Rei in Neon Genesis Evangelion and I think in the new movie again.
