HEAVEN SENT SPECIAL!
◾ BOJUN REY GUNN asks: After Heaven Sent, does the Doctor have 4.5 billion years’ worth of memories? He says he can remember ‘it all’ at the end of every cycle, which leads me to believe he can remember every second of it, but some people think that he only has memories of the last iteration. Also – how long did each cycle last, from the Doctor’s perspective?
