Funnily enough, I saw exactly how Cindy managed to use the butt of her sword to smack it right on Brian's temple before she got tackle-speared into oblivion, making both of them tumble badly on the floor. However, with how Cindy's face was still drenched in water and bits of spaghetti sauce, she kept hitting Brian with the butt of her sword as she was trying to wipe her face with her sleeves.
It's just that she had already scored a critical hit on Brian's temple and he'd sooner run out of saving throws to survive the day.
However, she soon realized she was hitting the wrong guy but another water balloon plopped at her forehead before drenching her again.
"WHAT THE FUCK IS THIIIIIIS?! COME OUT HERE SO I COULD STICK THIS S-STICK UP YOUR ASS! YOU— STOP THROWING FUCKING WATER BALLOONS AT ME!!!"
