Wow, is this the first ever instance of timelord regeneration gender-hop? I’m not sure.

What a fantastic episode, and I wonder if this will open the doors to a future female Doctor. Always thought Jessica Hynes would make a good female doctor.

I was left kinda confused by this, was kinda expecting to see a child Silence under the cover. Any other theories? I’m assuming it will be explained in later episodes, or did I just miss the point of that episode entirely?
