You'd think a fight for one's life (unlife, whatever) would be sufficient distraction from this bloody itch.

Mister Spiny's down for the count by now, but Spike's got his hands full with another guard plus one of the girls. He darts a glance at River, sees that she's holding her own, manages (with some effort) to keep it from turning into a much longer look, and concentrates on his own fight.
