Tam might have paid attention to the obvious display of stage magic. She also might have responded to her team leader. These were all important, relevant things that were happening. However, somewhat more relevant, was the fact that this pointy-eared primitivist asshat just shot one of her teammates. 

In another situation, Tam might have shot Fire. However, as much as she might clash with Fire, she also gave him a little bit of credit for being a teammate. That prevented her from killing him... for now. It did not, however, preclude less lethal methods of ensuring he didn't do it again. 

Muscles forged by a combination of heavy-grav environment and scientific intervention flexed, and a hundred-plus kilo's of Narakan flung herself at the shooter. What she might have lacked in finesse, Tam made up for in raw strength and years of experience in barside brawls and company-town riots. She hit like a train. Striking as the xeno casually checked his weapon, she attempted to disarm and grapple.

"Sarge! Get the fuck over here!" under the circumstances, she didn't bother with formalities, "Fucking Fire just shot Paul!"

 [Action: Disarm and Restrain Fire. @Nerminator: PM me if you wish to contest. Sorry, there is just literally no way someone could react casually to watching that happen]
