So much for all his vaunted combat skills. He hadn't even quipped well during the fight.
Oh Grayson, now is not the time, he admonishes himself lightly. Not that I haven't been in worse situations. And not that I'll ever enjoyed being tasered unconscious...
Restraints are old (if unappreciated) shoe, too. These are good and not easily escaped from. It would cost him broken, dislocated, and sprained appendages to get free, appendages he would need during the rest of his escape.
So he waits.
