Hi everyone, been lurking for long enough. Decided it was time to say hello.
I have to say I really enjoyed this episode. I thought it was a truly novel direction to take a companion’s story in – her becoming her own version of the Doctor.
Regarding the neural block and how it worked, I wonder if the clue is in the name – neural block. It blocks rather deletes, which leads me to think it could maybe work in a similar way to a perception filter. In Last of the Timelords the Doctor used a Tardis key to create a perception filter. When he wore the key round his neck Martha could see him but her eyes wanted to look away. As I remember it if a person approaches an object protected by a perception filter, they would instinctively walk around it without being aware of doing so. Could the neural block be similar? Directing the Doctor’s mind away from his memories of Clara, while his subconscious mind instinctively reacts to them, enabling him to remain the person Clara helped him to become.
