There was just regular hashira meeting when out of the blue, Muichiro broke down crying...

Giyu: "Muichiro-?" Rengoku: "What's wrong??" Tengen: "Is everything alright?" Sanemi: "Shut up! We're having a meeting!" Gyomei: "Sanemi, calm down. What's going on?" Mitsuri: "Muichiro's suddenly sobbing!"

(sorry if this seems out of context ;))
