This is a Russian spoken line lasting about fourteen seconds, built around a fond admission about G-Man, delivered with a drawn-out pause before the name lands. The voice sounds sincere and slightly sheepish, as if the speaker is confessing an unexpected favourite. It feels playful and warm, turning quiet admiration into a small, knowing joke that game fans will recognise instantly.
