It’s going to sound harsh, but I’m glad that this didn’t get filmed. It’s sentimental claptrap, it’s derivative of Blink in the extreme. I don’t feel it adds anything. It wouldn’t act as an emotional bookend to The Angels Take Manhattan and it would undermine the next episode if it was put at the end of The Power of Three, so I totally agree with the production team not filming this one. A close shave!
