Edward has talked his mouth inside out and now he has no mouth at all!
Here is a man who had mastered the pernicious art of conversation-murder, using his knowledge (and not his wisdom, for he has none) to garrote the innocent and the intrigued; to pounce upon idle chatter and suffocate the life out of it; to drain a topic of its curiousness (for that is a subject’s lifeblood!) and leave only a dried and dusty husk-like corpse with not even enough flesh for pedants to pick at.
Ignore the tears collecting in his eyes. He was warned this may happen. Serves him right.
