Hidan and Kakuzu already finished their second mission, when Kakuzu wanted to speak to Hidan, Hidan tried to make his ritual again. Kakuzu rolled his eyes and yelled at Hidan

Kakuzu: "We don't have time for your stupid ritual! You could at least stop talking for a second!"

Hidan: "Oh, come on! I only want to finish my ritual, It is more important to serve the great god Jashin, than going on a damn mission!"
