Re: 7X10 Journey To The Centre Of The TARDIS(Grading/Discussion)(SPOIL
Eye of Harmony, I can accept this as being what was under the Cathedral from the '96 movie. I always thought that the eye was a a Black Hole that that all Tardis tied into, not a star on the verge of being one. Either it's always been that, or did the Doctor refit / change the Eye at some point to break free of the original Eye?
He probably lost access to the original Eye when Gallifrey was time-locked; we know that during the first few years post-Time War, he had to refuel at the Cardiff Rift. It could be that the TARDIS gained a standalone Eye either when the TARDIS regenerated in "The Eleventh Hour" or when the universe regenerated in "The Big Bang".
