Harry exits the Pensieve and leaves Dumbledore's office.
He finds Ron and Hermione on the stairs and tells them he's going to the forest. Ron protests, but Harry insists, explaining that there's a reason he can hear the Horcruxes whispering.
Hermione seems to get it and starts to cry.
She wants to go with Harry, but he tells her to focus on killing the snake.
Harry and Hermione hug, and Ron and Harry share a last look. Looks like this is goodbye.
