The clip is a short spoken Lithuanian line, lasting about four seconds, delivered in a calm, matter-of-fact voice saying that everything is clear. It lands with a dry, conclusive feeling, as if a long explanation has finally ended and no reply is needed. The tone is flat rather than excited, which makes the ending feel settled and a little smug.
