Nearly everyone heard some shuffling of chain links or movement on the other side of the door .... nearly everyone, that is, except Zepsus and Donovan, who are both surprised.

Surprise Round ...

S22:
Bile, with catlike senses and reflexes, you are neither surprised, nor do you surprise. You have a bow in hand. (I assume you would have put the dagger away by now, because at last count you had a bow and a dagger in your hands.) You are currently in body of the night. The front two prison guards have sword and shield, and the others have bows nocked and ready. You have a MA or a SA available. What do you do?
