Sam's green lightsaber hums, whirls, crackles against the red of one Sith and the yellow of the other, thrust and parry and twist and dive and emthere/em his signal: two blaster bolts sizzle past Sam's ear and take the second Sith between the eyes as Sam knocks the head off the first one's shoulders. Both corpses are wide-eyed, betrayed Sam's lightsaber is the only one still on. Sam switches it off and gives Dean a thumbs-up without looking; no one's ever accused Winchesters of playing fair.
