Things got bad real fast. 

At first Donny thought he and Raa were actually getting through the turian. She seemed to be lowering her weapon, maybe even considering taking up their offer. But then one of the turians said something and caused her to shoot. Raa ducked, and Donny froze up. At that moment he felt days turn into weeks turn into months turn into years. He closed his eyes and let out a single tear. [b][i]"Sorry everyone..."[/i][/b] 

But Donny didn't feel anything. The bullet didn't hit him. Did she miss? Did she shoot someone else? Donny opened his eyes and saw Voria next to Raa. No blood from either of them, so Raa wasn't dead. Donny didn't see any of his blood... Though he may simply be running on adrenaline. He looked up at the turian. She was crying, but in her hands was a smoking gun. Donny had to act; he didn't have time to think of the danger. Since he was already so close he reached out and grabbed the barrel of the gun, jerking it upwards. His other hand moved towards the turian's neck as he moved into her. Grabbing her by her shirt Donny moved his leg behind hers, and just as he pushed her head down he swept her feet out from under her, to slam her onto the ground. Not exactly a "Non-lethal" maneuver, but he wasn't aiming to kill her. Simply take her down. He made sure the gun wasn't pointed at anyone as he pinned her to the ground.
