[ There's a huge exposed pipe linking this roof to the side of a much taller building about half a block away, and Mel hops onto it and starts walking along it backwards so she can face Ed, counting down from three on her fingers as she explains. ]

Marks: people I'm paid to grab from. Killing them is bad for business. Getting seen by them at all is bad for business. Showing up on their sec cams, also bad for business. Do not make direct contact with marks. Get in, get out.

Lurks: vampires, literally. Murder them and they go poof in a cloud of dust. Don't murder them and they eat people. Easy choice.

Enemies: please tell me you know this one. Rutters trying to kill me, or they came after my people. Doesn't matter if they're demons, humans, whatever. They come for me and mine, I kill their asses.
