You guys were inside a building in the Entertainment District, talking about the mission

Tengen: I brought you four here to help me find my wife- he got intorrupted by Zenitsu

Zenitsu: You brought us here to help you find a wife?? Do it yourself you god damn lazy-! Zenitsu suddenly got punched by Tengen

Tengen: NOT LIKE THAT YOU MORON!

Inosuke: Your wife's probably already dead Inosuke got punched too

(I made this interaction by memory so forgive if it's somewhat wrong lol)
