Shadower 

An individual whom follows around others to the point one could assume he or she was a shadow.
Shadower's can be obnoxious in a sense they feel what they're doing is not harmful. And yet to realize they're following individuals awkwardly.

Luke: Hey you did you go to the bar last night?
Bob: Yeah, but i was being shadowed again by you know who.
Luke: Louie?
Bob: Yeah i couldn't even talk to Shelly last night cause he was such a shadower.

shadower 

The one who knows your every move before you think about making it, the one who follows your every step when you make it, the one who is waiting locked and loaded and ready to frag your ass when you turn around.

Shadower followed the unsuspecting person all the back to base and fragged his ass!

this day and age, things change so fast that the centrifugal force of progress will shear your head right off. Shadowrunners like us need to keep up with the latest developments. When you run a B&E, you need to know what nasty new security feature might try to cut you in two as much as you need to know which nova new magic formula is worth snatching. It's the state of the art, chummer-it'll make you cred or get you dead."
