Was Sherlock at his own funeral in disguise at the end?
I wouldn't put it past him. I'm sure he'd like to hear his own eulogy. Straightedge means I'm better than you.
And what was being said from person to person?
Did anybody check the Priest
Could you post a picture of him as the priest?
He could have been anyone : he was a Master of disguise. Hell, he even played a Chair convincingly
Yes.
