Thel 'Vadam in the Forerunner Ark's Citadel, impaling the Prophet of Truth -- the self-proclaimed "voice of the Covenant" -- with an Energy Sword. During the cutscene, a squeal could be heard when the Prophet's screaming stopped, indicating the death of the Flood Infection Form that had just begun to take over his body.

The screenshot was taken from a cutscene near the end of Halo 3's Campaign level The Covenant.
