Before Sasha got close to Beatrix, Joshua blocked her path with his sheathed sword.
"Stay there." He ordered. His carefree attitude was gone, now replaces by an ice cold seriousness. Turning back to Beatrix, he spoke in a calm yet heated tone." I would take their advice. Leave here otherwise..."

Joshua moved and he moved quick. In the blink of an eye he covered the distance between himself and Beatrix, unsheathed his blade, and pressed it against Beatrix's neck.
"... you won't leave here unharmed. Now, kindly escort yourself out of here, or I'll drag you out." He finished, moving the blade just enough to draw a single drop of blood.
