I mean, the doctor long being dead wasn't exactly surprising.
To find his corpse (or rather the remains) neatly stored away like that though...
Nevermind a crow picking a key out of someone's wrist and cleanly guiding them there.
A fictional story's fictional for a reason but I preferred the rather realistic way things went before.
Then again, the occult has been mentioned before and reincarnation isn't exactly commonplace either so maybe someone felt the need to add a supernatural label...
