Kaiser knew he shouldn't proceed unarmed, so he stepped back, but stopped athward the entranceway when he spotted something in his peripheral vision.
He looked back once again to see something bouncing on the ground. He could have sworn the thing is familiar, so he moved closer to check until it settled down the floor; the only choice he had to make is whether to take a good look to make peace with his confusion or left completely.
"Nah," Kaiser scoffed and choose the latter. He wanted to keep his cool and stay away from the things that could potentially put him into trouble. They have to play safe now that they are already given their last chance to straighten up their plans.
