Enjoyed the episode on the whole. Think I would have liked some kind of big reveal as to who or what the Hybrid was a la John Hurts appearance in NoTD rather the current uncertainty, is the Hybrid really just a myth?
I think the most logical is Ashildr’s final theory, with the Hybrid being Clara and The Doctor. Half Dalek Half TimeLord, is it possible the legend classed Clara as a dalek due to her extensive links with them? Technically one of the claricles was a dalek…
On the flip side not sure if anyone else has picked it up but towards the end of the episode Clara says the following: “Memories become stories when we forget them, maybe some of them become Songs?”
Is that just another Moffat tease? Surely we haven’t seen the last of Clara?
