It's dark outside. It would be pitch black, but there are neon signs advertising so-and-so's open store, hot wings, and some street lights. So you can see the broken windows, the filthy street, and the general dilapidated area of the shady alleyway you're in.

Being bait is the worst part of the job, but the werewolf you're hunting won't go after Dean (not this guy's M.O., apparently.)

So now you have to be the one walking down the alley, while Dean sits pretty in the car watching, waiting for something to go down.

But he doesn't have to wait long, because the howling starts. Full moon, howling. Cliché.
