The Panopticon/Revision of the trenzalore
if the doctor survives we must take into account that the tomb wasnt an Alternate timeline but just was there for unknown reasons since if it never existed then clara would of never met the doctor and the doctor would of never left gallifrey
now czechout plz dont delete since i need to dicsuss more about this topic
it is possible the grave somehow exists from the alternate timeline but here i am only here to talk about the editing and not the speculation i think we can go to the howling
since if the grave didnt exist then the whole thing in the doctors life would collapse wouldnt it there would be no claras and no doctor in his tardis
discuss here
