When Jonas shows up at The Giver's room, the old man is crumpled in pain. Jonas readies to leave, but The Giver begs him to take some of the pain, which he willingly does.
This time, Jonas receives the memory of a body-strewn battlefield. He himself is lying on the ground and seems to be missing a good chunk of his arm, and he's forced to watch a comrade beside him slowly die.
When he can't take anymore, Jonas opens his eyes and returns to the room with The Giver.
The Giver apologizes for having transmitted such an awful memory, and he looks away from Jonas.
