In Doctor Who episode Before the Flood, the Doctor’s
ghost
does 3 things:
- Repeats the names of the crew in the order in which they will die
- Delivers the “chamber will open tonight” message
- Opens the Faraday cage
I understood 1 and 2: 1 so that the Doctor would be compelled to break the rules of time (or whatever) to save Clara; and 2 so as to give himself the idea of entering the suspended animation chamber.
But why did he open the Faraday cage? What did that achieve?
