This is a Russian voice line lasting about ten seconds, delivered in Dante's dry, unimpressed tone as he repeats the phrase for a bold claim. It feels amused and slightly mocking, like a raised eyebrow turned into sound, perfect for calling out something overconfident without raising your voice. The line is credited to Dante.
