They were locked in a straight and narrow now, the alley long, and few other obstructions for the man to hide behind, not that he thought he would. He brought his umbrella around, snapping it up and twisting the handle to "Stun". He slid into a kneeling position, pulling a trigger hidden in the curve of the handle. There was a soft escape of air as the umbrella fired the dart, Eggsy snapping it closed and taking off after the man again, who fell down twitching.
