All Byte can hear as he makes his way around the side of the house is the -POP! POP! POP!- of pistol fire, until suddenly, the routine is broken by the -BUDDABUDDABUDDA!- of fully automatic weapon fire. You don't remember either of your companions packing anything like that and you fear for the worst.
Viso sees the whole thing happen and knows what's coming, but his orkish "bodyguard" is just too fast for him to stop it. After taking a massive chunk out of one ganger and keeping another one off balance long enough for you to put a solid round or two through his jacket, FP foolishly charges up the stairs toward the threatening voice. Making good on her threat, she fills the stairway with APDS rounds, quite a few of which punch their way straight through your companion's armor vest and splatter a good amount of his blood all over the wall behind him. The look on his face says he's hurt bad, but still has a lot of fight in him. From upstairs, you hear a heavy door slam and Destiny screams from behind it, "The fukkin cavalry's own thar fuckin way, yew motherfuckers! You best git outta hyar!"
This might be the worst FP has ever been shot. At least the good news is, he's pretty sure there's no lead inside him still. They were all clean, in-and-out shots. But damn, does it hurt.
