With all the horcruxes found, Dracnar forced every single soul shard into the body Voldemort had retained the last of himself; Quirinus Quirrell. When each shard entering, the anguish upon Quirrell’s face in seeing the horrors before him of the man who still possessed him was shown. The screams for it to stop, because it was doing more than destroying him mentally, it was annihilating him physically, as he lost more and more of himself, and became quieter and quieter, until when the final shard was pushed through, Quirrell’s entire being was no longer, instead it had been remodelled to how Voldemort once was before he started tearing his soul into pieces.
