The shock of the grenade sends Billy reeling, an intense sensory overload overriding all attempts at analysis for almost a minute. The only instinct that registers in his brain is to move, move, MOVE. There won't be time to think if you die first, Billy.

Finally, he manages to re-orient himself in a world of flying knives and bullets. When did the crew become so vengeful and violent? Highly disadvantageous situation. Without a weapon, all he can really do is flip out of the way. For now, there's a dark shape diving around the tables, all the while trying to organize his priorities:

1. Locate and attempt to utilize a large distraction or environmental disturbance that has the capacity to disrupt the battle.
2. Find allies. Hopefully there's someone left who still doesn't prefer to make attempts on their lives. And while he's at it, he could try to figure out why this is happening too.
3. A weapon for defense would be a favorable asset as well.
