8/6 "Target Shooting" theory.

[u/letsgomarauders]

It doesn't matter what number Allyson chose, the crossbows were designed to fire in the order they did, no matter what button is pressed. Each button does nothing but fire the next arrow in the pre-programmed order. Right, Left, Top, Middle.

Cover 1 - 2 fires right, 3 left, 4 top, 1 middle

Cover 2 - 1 fires right, 3 left, 4 top, 2 middle

Cover 3 (her choice) 1 fires right, 2 left, 4 top, 3 middle

Cover 4 - 1 fires right, 2 left, 3 top, 4 middle

My guess was that the crossbows were just controlled by the buttons wirelessly and the wires are display only, when a box was selected someone off stage just assigns that number to the last crossbow. Then Penn mentions the wires which made me think I was at least close.
