Silence: Holding out for a double-cross

First, I'm assuming there is some sort of light source in the tunnel. Else, how could Eddie see me?

As for initiative, Kaspar rolls only a 5, for a total of 7.

After throwing his rock, Kaspar does in fact turn his back on the scene. However, upon hearing Fast Eddie's voice, the half-orc pauses. He turns on his heel, silently. Staring off down the tunnel, it is Fast Eddie's clothing that first catches Kaspar's eye. Then it's the tip of the rapier. Then, Fast Eddie's unmistakable grimace.

Without a word, Kaspar backs away -- back toward the ladder and Castille. He does not raise his sword. He does not even so much as gasp in surprise. Hoping that the shadows are dim enough to obscure Fast Eddie's view, Kaspar instead holds his course, waiting for his employer to make the first move.

If he makes the ladder before Eddie demands an answer, then Kaspar will count himself lucky and descend. But in his mind, Kaspar knows that he won't make it even half that far before his surprise will have to give way to shrewd words.

Castille, on the other hand, knows that trouble is afoot. When the sound of the catwalk collapsing reaches his pointed ears, he immediately begins to look about for intruders. Thoughts of Kaspar lying dead in the tunnel above briefly flitter in his imagination. Castille's injured companions shift. But the half-elf raises a finger to his lips, calling for silence. Then he motions for them to stay.

Castille moves towards the entranceway leading to the retention vat. He will peer around the corner, just barely enough to inspect the tunnel. All the while he will be sure to keep his light held back and out of view. Merrick is still holding the sunrod.
