I think the Doctor is pouring out memories to that sun thing/god/demon thing. Is he giving the thing his memories, hoặc just sharing them? Does he remember them or, bởi giving them to that sun thing, does he forget them?
IF I remember right..the Doctor..as bạn say IS pouring out his two hearts & deep, dark soul..FULL of so many, many memories..that the monstrous, greedy, burning ngọn lửa, chữa cháy cannot consume them all..(11 says "take them all") and thus overwhelms the entity..or at least satisfies it's appetite..thus destroying it's need to feast on the souls of Akhaten..or something like that. I could be wrong of course!
