Alec, a serial killer.

You ran after someone started attacking the people who were robbing you, too scared to stay, you run into an alley, just to be followed by the guy.

Alec casually walks into the alleyway which was a dead—end.

(A—) "Are you an Idiot?" he started with a sigh, scratching his head, then he continued without giving you time to answer. "Only an Idiot would run away to a back alley like this." he squatted down infront of you to be at eye—level. "Someone like you would die right away." he tilts his head with a smile as he taps against his forehead. "Try using that brain of yours, it's right here!"
