Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 121
I do not feel that the following dialog:
"How did you destroy all but a remnant of the Dark Lord?"
Harry hesitated. "I Obliviated most of his memories and... sealed him, I guess is how wizards say it. Even if the seal breaks, he won't come back as himself."
Severus frowned briefly and then shrugged. "I suppose that is acceptable."
really fit with what Snape told sooner in the story:
"No," Severus said flatly. "The prophecy is not yet fulfilled. I would know if it were."
"Are you sure of that?"
"Yes, Potter. If the prophecy had already come true, I would understand it! I heard Trelawney's words, I remember Trelawney's voice, and if I knew the events that matched the prophecy, I would recognize them. What has already happened... does not fit." The Potions Master spoke with certainty.
I was expecting a more interesting reaction than just a shrug from Snape.

We do not know for sure. Here are the quotes:
from chapter 6
As his hand touched the back door's handle, he heard a last whisper from behind him.
"What?" Harry said, his hand still on the door.
"Look for a first-year girl named Hermione Granger on the train to Hogwarts."
"Who is she?"
There was no answer, and when Harry turned around, Professor McGonagall was gone.
from chapter 8
"Were you told to wait for Harry Potter on the train to Hogwarts, or something like that?"
"No," Hermione said. "Who told you about me? "
It doesn't look really like her style though.
