At night Hill accidentally almost shot Dauterive in the kneecap but he was reprimanded Bloobenhauer. Boxa Posta then arrived with the flag, Dauterive was instructed to show Boxa where the flag would be placed.
After Boxa dropped the flag over the cliff Dauterive was told calm down by Bloobenhauler and an agreemeant was made to pay for a replacement flag.
Every week Boxa would bring a new flag and drop it off the cliff leading him to stab her and kick her ass, Bloobenhauer would stop Dauterive from kicking Boxa's ass and as punishment he ordered him to act as target practice for Hill.
