Before he regenerated, did the Doctor actually STOP the creeping blot of entropy that was gobbling up the universe? Or did they just hope the Master actually did have a plan and fixed it, since the three companions raced off with the newly regenerated Doctor, forgetting all about the entropy? And did that entrophy blot remain, effectively having destroyed a good half of the known universe? Is that why, now, there appears to be only (or at least mainly) Earth?
I have a headache. I should have gotten up to go to the gym. I feel fat. It can't be hormones again already!
