He's really committed to the act, isn't he? Nary a twitch nor a change in breath even with the approach of a stranger. Shalem can respect that, especially the skill in acting. Pretending to be asleep or dead has always been one of the more difficult things to learn.

Be it far for him to not play along-- Shalem so does love a play.

The serpent stands, brushing himself off and straightening his clothes, ready to play the knight in shining armour, come to save the maiden with true love's kiss. Even if he's merely wearing a casual suit, he can still carry himself as if he were. Then he kneels down by the "sleeping" man, brushing his dark hair out of his face, and bends over to brush a soft kiss on the man's lips.

Just a soft one. Teasing him for his trickery.
