Master
Tatsunoko realized his situation was dire, and he had to do something quick if he wanted to pacify his unworthy servant.
Tatsunoko rolled towards his left again, dodging another sword strike by his servant, before thinking of the proper solution.
Tatsunoko rapidly grabbed one of the girls who looked like a servant, and he held her in a chokehold with in one arm, quickly drawing a gun from under his jacket, holding it against her head.
"Don't move or this girl will die... You wouldn't want that would you?" Tatsunoko said with a wicked smile as he put his finger on the trigger, ready to end the poor girl's life.

Servant
Mizore was still staring at Gilgamesh, not paying much attention to her surroundings.
"I wonder if he will notice me if I win the grail... I would only need to get rid of a few annoying people..." She thought, before somebody suddenly grabbed her by her neck in a chokehold.
She didn't have time to turn around and look who it was, but he noticed the huge paladin from before standing in front of her, so she quickly realized who was holding her as an hostage.
"Damnit... If he shoots they will figure out I am a servant and my entire plan will be ruined..." She thought to herself, as she started to make choking sounds.
She wasn't actually choking, as his hold wasn't exactly tight, but if she made a big deal out of it, she had a larger chance to be rescued.
